Owing to the toxicity of heavy metals, it is increasingly important to test cannabis flowers and other cannabis derivatives so that patient and consumer safety is maintained as the use of cannabis becomes more common. This need has translated into an increasing demand for testing cannabis flowers and other cannabis derivatives for toxins such as the heavy metals cadmium (Cd), lead (Pb), arsenic (As), and mercury (Hg). In this application note, we present data to illustrate the successful validation of the Titan MPS™ Microwave Sample Preparation System and the NexION® ICP-MS for the determination of heavy metals in cannabis flower according to the validation protocols set in USP General Chapter <233>, which are commonly used for evaluation of the levels of elemental impurities in samples.
Testing for the levels of pesticide and mycotoxins in cannabis is important to ensure consumer safety and quality control. In this work, the PerkinElmer application development team analyzed all 66 pesticides (including very hydrophobic and chlorinated pesticides typically analyzed by GC-MS/MS) and five mycotoxins spiked in cannabis flower extracts well below the action limits specified by the state of California. A LC-MS/MS instrument was used with ESI and APCI sources and a simple solvent extraction method with excellent recoveries for all analytes in acceptable range of 70-120%.
Liquid chromatography-tandem mass spectrometry (LC/MS/MS) has become the method of choice for pesticide. The state of Oregon has issued regulatory limits for 59 pesticide residues in both cannabis flower and concentrates, while other states have come up with their own lists of pesticide residues relating to medical marijuana and cannabis testing.
Solvent such as supercritical CO2, butane, propane, other hydrocarbons, water, or alcohol are used to extract out the cannabinoids and terpenes from the plant material. In some cases, the solvent and impurities from the solvent remain in the extracted material. This study will shows the analysis of residual solvents using pressure-balanced headspace (HS) sample introduction coupled with Gas Chromatography/Mass Spectrometry (GC/MS). Unambiguous separation of all compounds is obtained while maximizing sample throughput.
The use of cannabis concentrates and CBD products (edibles, topicals, vape products, etc.) has increased in popularity as new regulation has been passed legalizing medicinal and recreational use in a number of states and provinces. Testing to ensure that pesticide and mycotoxin levels in cannabis products are below regulatory levels is critical, however, the cannabis concentrate matrix presents many analytical challenges including higher sample matrix effects and an increased concentration of cannabinoids in the sample. In this application note, an LC/MS/MS method for the analysis of 66 pesticides (including hydrophobic and chlorinated pesticides typically analyzed by GC/MS/MS) and five mycotoxins in a cannabis concentrate matrix is presented. Utilizing a QSight® 420 LC/MS/MS instrument with dual APCI and ESI sources, the analysis yielded excellent recoveries and detection limits below those specified by the state of California cannabis regulations.
This work shows an on-site, rapid and low-cost technique for the accurate measurement of flower potency. FT-NIR spectroscopy provides rich information regarding the chemical composition of cannabis flower. When combined with chemometrics, the FT-NIR offers unparalleled speed and simplicity that cannot be matched by traditional techniques. PerkinElmer Spectrum Two NIR with the Near Infrared Reflectance Module (NIRM) is used to quantify total THC and total CBD in dried cannabis flower. The use of FT-NIR directly at the grow site would reduce overall research and development costs for cultivators.
Marker Assisted Breeding (MAB), a technique commonly used in agricultural industries, can be used by Cannabis breeders to associate regions of genetic variation (locus/ loci) with a specific phenotypic trait. Marker Assisted Selection (MAS), a selection process used in MAB where a trait of interest is selected based on a specific genetic marker, allows Cannabis breeders to select for specific characteristics such as yield, potency, vigor, disease resistance; potentially strengthening strains and enhancing crops through traditional breeding techniques.

The production of cannabis extracts and oils for medicinal and recreational products has increased significantly in North America. This growth has been driven by both market demand in newly legalized states and patient demand for a greater diversity in cannabis products.1,2,3 Most cannabis extraction processes, independent of solvent or instrument choice, undergo a decarboxylation step whereby the carboxylic acid functional group is removed from the cannabinoids. The decarboxylation reaction converts the naturally occurring acid forms of the cannabinoids, e.g. tetrahydrocannabinolic acid (THCA) and cannabidiolic acid (CBDA), to their more potent neutral forms, e.g. tetrahydrocannabinol (THC) and cannabidiol (CBD). Because the carboxylic acid group is thermally labile, the industry typically applies a heat source, and at times a catalyst, to decarboxylate the cannabinoids.
Inductively Coupled Plasma – Mass Spectrometry (ICP-MS) allows the analysis of a variety of food samples accurately for elements present at both trace and nutritional levels during the same analysis. PerkinElmer has been at the forefront of ICP-MS technology – from the very first commercial ICP-MS back in 1983 to the first instrument bringing together the detection limits of a true reaction cell and the simplicity of a collision cell in 2010, and most recently, the industry’s first four-quadrupole system – nearly four decades of patents, innovations, and accolades.
In recent years, to protect the health of consumers, more meticulous monitoring of food, more rigorous regulations with lower limits of quantification (LOQs) are required. The use of liquid chromatography tandem mass spectrometry (LC/MSMS) is widely recognized as the extremely sensitive and highly specific technique of choice for the determination of food contaminants at trace levels including pesticides, veterinary drugs, natural toxins, and so-called “emerging contaminants”. Our robust and reliable QSight® triple quad systems consistently deliver the throughput and productivity you need in your analytical testing lab. Our LC/MSMS solutions deliver the highest sensitivity and throughput the industry has ever seen and the capability to test for the most challenging, complex samples, including cannabis.

Agricultural growing of hemp products for the purposes of cannabidiol (CBD) extraction was legalized in the United States with the passing of the Agricultural Improvement Act of 2018. Since the act passed, heightened concern over the use of pesticides in hemp production has been appreciated. However, no federal guidance is currently available in the United States to standardize analytical methods for the detection and quantification of pesticide residues in hemp products. In this application note, a robust and efficient single-run LC/MS/MS method for the determination of 66 pesticides, including hydrophobic and chlorinated pesticides typically analyzed by GC/MS/MS, is presented. Utilizing a PerkinElmer QSight® 420 UHPLC with MS/MS detector and dual ESI and APCI sources, excellent recoveries in the range of 70-120% were achieved. The application note also outlines participation in an Emerald Scientific blind proficiency test, with acceptable results for all 66 pesticides.
Following the 2018 legalization of recreational cannabis usage in Canada, the quality and safety of cannabis products has garnered significant attention. Health Canada has developed a regulatory program mandating pesticide testing on all cannabis products. Under the program, licensed producers (LPs) of cannabis products in Canada are required to send representative samples of products to independent laboratories for pesticide screening and quantification. In this application note, a robust and reliable method for the analysis of 96 pesticides in cannabis flower by LC/MS/MS utilizing both ESI and APCI modes is presented. The method not only offers ultra-low detection limits at or below the Health Canada regulatory levels, but also offers significant efficiency gains over other available methodologies. Utilizing LC/MS/MS with both ESI and APCI modes obviates the need to perform both GC/MS/MS and LC/MS/MS analyses to analyze all 96 regulated pesticides, saving significant time and money for operators.

Analysis of moisture, fat, protein, salt, and pH is of great importance to cheese plants. Quick and accurate control of these constituents ensure product quality, help optimize processes and lead to significant savings for the producer. The Near Infrared Spectroscopy (NIR) technique is well-suited for cheese analysis, but past instrument limitations have not allowed users to reap the full benefits of the technology. This application brief demonstrates how PerkinElmer DA 7250 is ideally suited for analysis of moisture, fat, salt, protein content and pH of cheese with very high accuracy in only six seconds.
Cheese melting temperature and viscosity are important quality characteristics for processing and consumption of cheeses such as mozzarella. The melt characteristics of grated cheese can be measured in the RVA in the presence of a small amount of propylene glycol. The RVA parameters including temperature at melting, minimum viscosity and temperature at solidification are good indicators of the meltability of a processed cheese sample.
Analytical technologies from PerkinElmer help dairy farms, processors, and regulators authenticate and protect the integrity and quality of their products. Whether the threat is known or unknown, we offer a range of targeted and nontargeted solutions to aid in the fight against food fraud. And many of our milk analyzers work according to internationally recognized standards like IDF, ISO, ICAR and AOAC.
The value of milk powder is linked to its protein content, and standard methods for protein analysis rely on a simple nitrogen assay, with the protein concentration inferred from the nitrogen content. Consequently, the addition of chemicals rich in nitrogen can artificially increase the apparent protein and thus the price demanded. NIR spectroscopy clearly has a role to play, given its ubiquity in raw materials testing. The unique Adulterant Screen algorithm from PerkinElmer retains the strengths of non-targeted chemometric methods like SIMCA, but obtains greater sensitivity by utilizing a library of spectra of potential adulterants. The method can be easily adapted to screen new products or for new adulterants, without having to prepare mixture samples for calibration.
This work demonstrates the ability of PerkinElmer’s ICP-MS to effectively measure macro-level nutritional elements in the same analysis run as lower-level elements,without having to dilute the samples. The agreement between experimental and certified results for NIST® 1549 Milk Powder demonstrates the accuracy of the analysis. Instrument design characteristics eliminate deposition on the ion optics, leading to long-term stability in high-matrix samples, while permitting trace levels to be accurately measured.
Milk and milk powder are used widely in the food industry for the production of other foods. Because of its nutritional importance and widespread consumption, regulations in many countries necessitate that the quality of the milk is routinely monitored.
A practical screening method for the presence of melamine down to a level of 500 ppm or 0.05%m/m using Lactoscope FTIR is presented here. The discrimination limit can be further reduced to 100 ppm (0.01%m/m) using the melamine specific detection model.
The Near Infrared Reflectance (NIR) technique is particularly suited for measurement of dairy powders. In this work the DA 7250 shows very accurate and reproducible results when compared to the results from the reference methods.
Milk is an important source of nutrients, mainly for children. Because of its importance, milk is available in several different forms, most commonly as fresh, but it is also available in nonperishable forms (such as powdered and evaporated). Therefore, the requirement exists to analyze several forms of milk for nutritional elements. While ICP-OES is generally favored in a multi-element analytical environment, the cost savings, simplicity and speed of operation of a flame atomic absorption (AA) system provide an attractive alternative. Measuring multiple elements by flame AA requires each sample to be analyzed individually for each element, which impacts the speed advantage of flame AA – however, to address the speed issue, a fast, high-throughput sample automation system can be used. This work demonstrates the ability of the PinAAcle™ 900 AA spectrometer to reliably and effectively analyze common nutritional elements in a variety of milks over a wide range of concentrations. Coupling the PinAAcle 900 with the FAST Flame 2 sample automation accessory minimizes user error when performing dilutions and making calibration standards increases throughput and provides excellent long-term stability, increasing productivity for the laboratory.

The Rapid Visco Analyser (RVA) can perform high temperature tests. The method presented in this document is applicable to any liquid or hydrated ground material including, but not limited to, unmodified starches, flours, whole meals, gums, diary ingredients, and other formulations.
High temperature method applicable to starch and non-starch hydrocolloids including unmodified and modified starch, carboxymethyl cellulose (CMC), carrageenan, guar, LBG, xanthan and pectin in pure or mixed forms. Parameters such as viscosity and gel forming potential, shear thinning, time thinning (thixotropy) and thermal stability can be determined by this method.
This high temperature RVA method is applicable to any unmodifies and modified starches and their derivatives, including composites with hydrocolloids and lipids. High shear is used in the method to approximate typical processing conditions for these ingredients, which are commonly used as far replacers, gelling agents and stabilizers, and as paper wet end, size press and coating additives.
This high-temperature RVA method is designed to mimimc retorting, allowing assessment of the suitabilitu and stability of polysaccharide thickeners (eg. Gums, modified starches) in the formulation for high temperature processing.
The profiles in this method are modified from the procedures of Broadhead et al. (2004), using malted barley and wheat.In studying barley malt and modified malt samples for distilling performance, Broadhead et al. (2004) used a 30-minute heating profile on the RVA to successfully identify malts.
This procedure is based on the method of Goode et al. (2005) using malted and unmalted barley, to study the effect of endogenous enzyme and added adjunct levels, respectively, on mash viscosity. This profile can be used to check the suitability of a batch of grain for mashing, or for checking the appropriate level of added adjunct in the mashing system.The RVA is used as a laboratory-scale rheological tool for the characterization of mash viscosity, allowing the brewer to monitor the processes that are taking place during mashing.
Formulations for breads, cakes and baked products usually include a combination of additives to improve dough stability, texture and organoleptic qualities. Some of the more common additives include reducing and oxidizing agents, salt, sugar, enzymes, and emulsifiers. The effects of these additives on dough quality can be examined on the doughLAB, by comparing a sample with and without the additive. A longer test profile is used to allow for the strengthening effect of some of the additives to be fully observed.

Rice represents a dietary staple for over half of the world's population. However, in recent years, concerns have been raised over the presence of high levels of arsenic (As), where this carcinogenic metalloid can be accumulated at levels far exceeding ambient concentrations. Since China is the world's largest producer of rice, the Chinese government released a national standard method in 2014 for food safety – GB 5009.11– to aid the evaluation of As species in rice and rice products. In this document, HPLC-ICP-MS is identified as the preferred analytical technique. In this study, five arsenic species were characterized in a commercial rice sample and certified reference material using a gradient anion-exchange method in accordance with GB 5009.11. The analysis was performed using a PerkinElmer NexSAR™ HPLC-ICP-MS speciation solution, consisting of a NexSAR inert HPLC coupled to a NexION® ICP-MS.
Mycotoxins produced by fungi as toxic secondary metabolites, leave grains, maize and cereals particularly vulnerable. With this in mind, and considering that an estimated 25% of all crops show some signs of mycotoxin contamination, many countries have established regulatory guidelines for maximum mycotoxin limits in not only feed and grain, but also in processed food products.
Mycotoxins are toxic secondary metabolites produced by fungi, and are capable of causing disease and death in both humans and animals. Sample preparation is a critical step in the successful analysis of mycotoxins in food matrices. The "dilute and shoot" approach is a quick and easy way to introduce the sample into the LC/MS/MS analysis. However, due to the complexity of food matrices, this approach will often result in irreproducible matrix effects. To overcome these problems and improve sensitivity, this application note details the use of online solid phase extraction (SPE), coupled to an LC/MS/MS system for sample enrichment.
Lead (Pb) and cadmium (Cd) are common pollutants in grains and are extremely toxic. Pb is harmful to human organs even at trace levels, and once it accumulates in the body, it causes inhibition of hemoglobin formation and neurological disorders. Cd is even classified as human carcinogen [Group 1 - according to International Agency for Research on Cancer]. It is reported that Cd leads to severe kidney problems which can be fatal and is also associated with brittle bones and liver problems. Rice, as the most widely consumed cereal grain in Asia/China, can quickly pick up Pb and Cd from toxins, pesticides and fertilizers in the soil, thereby endangering the health of millions of people through their diet. Therefore, it is extremely important to develop a simple, reliable method to monitor the levels of Pb and Cd in rice. According to Chinese national standard GB 2715-2016 Hygienic Standard for Grain, the maximum concentrations of Pb or Cd in grains must be below 0.2 mg/kg; the allowable level in the European Union is the same [EC 1881/2006]. The official technique for the determination of heavy metals in both cases is graphite furnace atomic absorption spectroscopy (GFAAS, GB/T 5009. 12-2017, GB/T 5009-2017. 15 and EN 14083:2003). Samples can be pretreated using various methods, including microwave digestion, hot block digestion, dry ashing, and hot plate digestion. It is found that these conventional digestion procedures are always complicated and time-consuming (two-four hours or even longer). Plus, conventional sample preparation techniques require large quantities of corrosive and oxidizing reagents, increasing the chance for contamination which could lead to inaccurate results. Special PTFE vessels are needed for microwave digestion; however, reusable utensils might also cause cross contamination.

During the frying process, palm oil undergoes a series of degradation reactions, caused by heat, water and air, which results in oxidation of the oil and can ultimately reduce the quality of the oil and cause adverse health effects for consumers. The extent of oxidation in the oil can be assessed by determining the peroxide value (PV). Generally, the lower the PV, the higher the quality of the oil but very rancid oils, with high levels of oxidation, may have a reduced PV due to peroxides decomposing to form aldehydes and other secondary oxidation products. The acid value (AV) measures how many fatty acids have been cleaved from their parent molecule due to hydrolysis, which may result from the oxidation of the peroxides.

Polycyclic aromatic hydrocarbons (PAHs), a class of complex compounds containing two or more benzene rings, are widely found in the environment and food. PAHs are formed during the incomplete combustion of organic matter, such as wood utilized in cooking and food preparation. They have attracted wide attention due to studies which have shown the teratogenicity and carcinogenicity of PAH compounds. For humans, food intake is one of the main sources of PAH exposure, and can be the result of contamination from anthropogenic sources, food processing or cooking practices. In this paper, a validated method employing accelerated solvent extraction (ASE) and gel permeation chromatography (GPC), followed by solid phase extraction (SPE) on silica and analytical determination by GC/MS was applied for the detection of PAHs in smoked meat.

Lead (Pb) and cadmium (Cd) are common pollutants in grains and are extremely toxic. Pb is harmful to human organs even at trace levels, and once it accumulates in the body, it causes inhibition of hemoglobin formation and neurological disorders. Cd is even classified as human carcinogen [Group 1 - according to International Agency for Research on Cancer]. It is reported that Cd leads to severe kidney problems which can be fatal and is also associated with brittle bones and liver problems. Rice, as the most widely consumed cereal grain in Asia/China, can quickly pick up Pb and Cd from toxins, pesticides and fertilizers in the soil, thereby endangering the health of millions of people through their diet. Therefore, it is extremely important to develop a simple, reliable method to monitor the levels of Pb and Cd in rice. According to Chinese national standard GB 2715-2016 Hygienic Standard for Grain, the maximum concentrations of Pb or Cd in grains must be below 0.2 mg/kg; the allowable level in the European Union is the same [EC 1881/2006]. The official technique for the determination of heavy metals in both cases is graphite furnace atomic absorption spectroscopy (GFAAS, GB/T 5009. 12-2017, GB/T 5009-2017. 15 and EN 14083:2003). Samples can be pretreated using various methods, including microwave digestion, hot block digestion, dry ashing, and hot plate digestion. It is found that these conventional digestion procedures are always complicated and time-consuming (two-four hours or even longer). Plus, conventional sample preparation techniques require large quantities of corrosive and oxidizing reagents, increasing the chance for contamination which could lead to inaccurate results. Special PTFE vessels are needed for microwave digestion; however, reusable utensils might also cause cross contamination.

They have attracted wide attention due to studies which have shown the teratogenicity and carcinogenicity of PAH compounds. For humans, food intake is one of the main sources of PAH exposure, and can be the result of contamination from anthropogenic sources, food processing or cooking practices. In this paper, a validated method employing accelerated solvent extraction (ASE) and gel permeation chromatography (GPC), followed by solid phase extraction (SPE) on silica and analytical determination by GC/MS was applied for the detection of PAHs in smoked meat. The results demonstrate that the method is suitable for the simultaneous determination of 24 PAHs in smoked meat with good efficiency, accuracy and reproducibility.
Polycyclic aromatic hydrocarbons (PAHs) can contaminate foods during smoking, heating, and drying processes that allow combustion products to come into direct contact with food. They can also enter food supply chains through contaminated air and water, and accumulate in various food chains. Regulations are in place to monitor PAHs levels in foods; the EU set a stringent maximum residue limit (MRL) for BaP in muscle meat of smoked fish and smoked fishery products at 2 µg/kg.2 In this study, seafood samples were prepared using a QueChERS extraction method followed by a dispersive solid-phase extraction clean-up step. The samples were subsequently analyzed by coupling a UHPLC system with a triple quadrupole mass spectrometer.
Nitrofurans are a class of broad-spectrum antibiotics that are widely used to kill or slow down the growth of bacteria in the aquaculture industry. The use of nitrofurans and their metabolites has been restricted by a number of countries and organizations within the European Union, United States and China, due to their harmful side effects to human health, and a Minimum Required Performance Limit (MRPL) 0f 1.0 µg/kg has been set for food, animal and aquaculture products. LC/MS/MS methods have been used for the detection of nitrofuran metabolites in many studies owing to the high sensitivity, selectivity and specificity of the methods. However, nitrofuran metabolites demonstrate low ionization efficiency with the electrospray ion source used in LC/MS/MS systems. Therefore, the use of a derivatization step for nitrofuran metabolites before extraction and LC/MS/MS analysis is crucial to meet the low regulatory limits of 1.0 µg/kg in food samples. The main purpose of this work is to determine the detection limits for nitrofurans using QSight® 210 LC/MS/MS system.
Beta-adrenergic receptor agonists (ß- agonists) are synthetic drugs utilized in the treatment of conditions such as asthma in humans, and are also used as a growth-promoting agent in food-producing animals. The use of ß- agonists in food-producing livestock has been either banned or regulated across many countries owing to human health concerns. To aid in the monitoring and detection of ß- agonists in livestock, a highly sensitive and selective analytical method has been developed, and is presented in this study. This LC/MS/MS method details the analysis of 13 ß- agonists in pork samples, and utilizes isotopically-labeled internal standards to compensate for matrix effects present in complex food matrices.
Polycyclic aromatic hydrocarbons (PAHs) are hydrocarbon molecules containing two or more aromatic rings. Some PAHs, such as benzo[a]pyrene, are classified as carcinogens. There are concerns about PAHs in food, especially in grilled meats. This application note presents a method developed to measure 15 + 1 EU priority PAHs at low levels using gas chromatography mass spectrometry (GC/MS). It also describes a reliable procedure for extraction and purification of PAHs from meat samples. The sample preparation will focus on benzo[a]pyrene. In addition to method optimization and calibration, a variety of meat samples are analyzed and the amount of PAHs determined.
