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%.
Acrylamide is a probable carcinogen organic compound that is found in some foods that are cooked at elevated temperatures. It’s origins are due to the condensation of the amino acid asparagine and glucose as part of Maillard reaction. In 2002, Acrylamide was found to be present in french fries and baked bread. This compound has now also been found in some other food stuff like coffee, black olives, dried pears, and peanuts. As a result the and World Health Organizations have promptly limited its presence for human consumption.
Aflatoxin B1 is considered to be the most genotoxic of the mycotoxins, and, when ingested by cows, is converted to aflatoxin M1 which has been shown to cause liver cancer in certain animals.
Benzo[a]pyrene (B[a]P) is a well-known carcinogenic compound found in tobacco products and tobacco smoke. The Cooperation Centre for Scientific Research Relative to Tobacco (CORESTA) has recommended a gas chromatography/ mass spectrometry (GC/MS) method to determine concentrations of B[a]P in tobacco products. In the proposed method, B[a]P is extracted from the tobacco with methanol, followed by a solid phase extraction (SPE) and subsequent concentration prior to GC/MS analysis. The CORESTA recommended method is time-consuming, especially in sample preparation procedures, and showed low sensitivity. In this application note, a simple, reliable and fast analytical method for the determination and quantification of B[a]P in tobacco products has been developed using a PerkinElmer QSight® LX50 UHPLC system, coupled to a PerkinElmer QSight 220 MS/MS detector.
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.
Pharmaceutical and Personal Care Products (PPCPs) are an emerging environmental concern, and include human and veterinary prescription and over-the-counter medications, sunscreens, lotions, soaps, and insect repellants. These commonly encountered products can enter the environment through various sources, including municipal wastewater, polluting ground water, surface water, and even drinking water. The analytical challenge associated with PPCP testing is the wide variety of chemical classes/ types that are typically present at parts per trillion (ng/L) concentrations in drinking water. The automated approach described in this application note allows for significant and efficient analyte concentration, obviating the need for elaborate and time-consuming sample preparation procedures, and thus improving productivity, reducing solvent usage and laboratory waste.
Per- and polyfluoroalkyl substances (PFAS) are man-made carbon-chain based compounds that have been widely used in commercial and industrial products such as fire-fighting foams, water proofing treatments for clothing and furniture, nonstick cookware, and paper. PFAS’ are thermally and chemically stable, and resistant to degradation, making them ideal for many applications, but also allows the chemicals to bioaccumulate in the environment, leading to a designation as a contaminant of concern to human health and wildlife.
US EPA promulgated SW-846 Method 8327 for the analysis of PFAS in four non-potable aqueous matrices using external standard calibration and liquid chromatography/tandem mass spectrometry (LC/MS/MS). In this application note, a fast and robust method for the analysis of all analytes listed in EPA Method 8327 is presented, using a PerkinElmer QSight® LX50 ultra high-performance liquid chromatography (UHPLC) system coupled with the PerkinElmer QSight 220 triple quadrupole mass spectrometer.

Since 2003 the usage of azo and non-azo dyes for food coloring has been declared as illegal by many of the food international authorities across the globe. That is because these substances such as Sudan I,II,III,IV and Rhodamine B, are potentially carcinogens and genotoxin in nature. As of now, no official methods have been published for the detection of illegal dyes however, the most used analytical technology is GC-MS or HPLC coupled with UV or MS detection.
Veterinary drugs are utilized extensively in modern day farming to prevent and treat animal diseases. However, use of these drugs must be carefully monitored, and failure to regulate the presence of residual veterinary drugs in animal tissues could pose a risk to human health if animal tissues with residual veterinary drugs are consumed. Many regulatory bodies, including the US FDA and Health Canada have developed maximum residue levels (MRLs) for residual veterinary drugs as a means to safe-guarding human health.
In this application note, a robust, high-throughput method for the analysis of 73 veterinary drugs in chicken tissue is presented. The method utilizes a fully automated solid phase micro-extraction (SPME) sample preparation technique, with subsequent analysis on a QSight® UHPLC/MS/MS.
Aflatoxin B1 is often found in animal feeds such as corn, cottonseed cake, groundnut meal, and other agricultural commodities. When these contaminated feeds are ingested by milk-producing animals, such as cattle, aflatoxin B1 can be converted to aflatoxin M1 (a hydroxy derivate of aflatoxin B1) by oxidation metabolism, and then excreted in milk. To protect consumers from the potential toxicity and carcinogenicity of aflatoxin M1, regulatory agencies have established regulatory limits or action levels for aflatoxin M1 in milk products.
In this study, a simple, fast, selective and sensitive LC/MS/MS method for the analysis of aflatoxin M1 is presented, along with the evaluation of three sample preparation methods.
Coumarin (1,2-benzopyrone) occurs as a natural component in some plants, and is utilized as a flavoring ingredient in some foods, tobaccos and cosmetic products. In recent years, coumarin has been added to electronic cigarette liquid nicotine solutions as a flavoring component, producing a complex flavor profile with aromas of vanilla, almond, cherry and cinnamon. Coumarin has been found to exhibit hepatoxic effects, and has been banned by the FDA in food products, but this ban does not extend to tobacco products, such as electronic cigarettes.
This application note details a method for the analysis of coumarin in electronic cigarette liquid nicotine cartridges, utilizing PerkinElmer UHPLC system coupled to a QSight® 220 triple quadrupole mass detector with a dual ionization source.
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.
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.
Antibiotics are used in dairy cattle for different treatments, but it leads to accumulation of these residues in milk. Presence of such residues in human food can be responsible for allergic reactions, toxic effects and develops resistant strains of bacteria. To protect consumers, regulatory agencies in the European Union published several official documents to regulate the control of veterinary drugs. Council Directive 96/23/EC establishes the veterinary residue control in food producing animals. In India, as per FSSAI (gazette notification dated 20th July 2018) and EIC (RMP for Aquaculture, Egg, Honey, Milk Poultry etc.) it is a mandate to do the analysis of antibiotics. EIC and FSSAI both have maximum residue limits (MRLs) for various antibiotic residues for food matrices from animals. It is essential to test milk for residues of sulfonamides considering safety and prevent exposure of consumers to veterinary drugs. In this work, we present a fast and sensitive LC-MS/MS method for the quantitative analysis of sulfonamides antibiotics in milk.
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.
In this work, we present a fast and sensitive LC/MS/MS method

Using time-managed- MRM™ in the QSight™ triple quadrupole mass spectrometer, the optimum dwell time of multiple MRM transitions can be generated automatically for the targeted analytes. This not only saves time in method development but also improves data quality and analytical performance of instrument.
Endocrine disrupting chemicals (EDCs) have been found to have harmful effects on the health of both humans and wildlife. Of these EDCs, endogenous estrogens, such as estriol, 17ß-estriadiol, and estrone are of particular interest due to their potency/physiological activity even at very low levels. These hormones are particularly challenging to monitor, as concentrations are typically expected to be in the low ng/mL (ppb) to low pg/mL (ppt) range.
To improve sensitivity, this work utilizes the addition of on-line solid phase extraction (SPE) coupled to an LC/MS/MS system for sample enrichment and quantitation. This approach allows for significant/efficient analyte concentration, obviating the need for elaborate and time-consuming sample preparation procedures. Due to enrichment, compared to other methods, large sample volumes (= ½ liter) are no longer needed to reach part per trillion levels for estrogen monitoring in river water.
Drugs of abuse, which can trigger the user’s central nervous system and induce an altered state of mind, can be divided into different types, including stimulants such as cocaine, psychoactive substances such as LSD (lysergic acid diethylamide) and marijuana, and painkillers such as morphine and heroin.

Unintended releases of aniliane or its derivatives into the environment pose a serious threat, with release possible during any stage of production, storage, transport, use, or disposal. Therefore, it is important and necessary to develop fast, simple, sensitive, selective and efficient methods for the determination of aniline and its derivatives in drinking and environmental waters. The aim of this study is to develop an LC/MS/MS method for rapid analysis of aniline and its derivatives in water samples by direct injection, without using time consuming sample preparation steps.
Cartridges containing cannabis extract or CBD are some of the cannabis industry’s fastest-growing major product categories. It is imperative that the composition of these products is understood to ensure that components in the product do not contribute to e-cigarette or vaping product use-associated lung injury (EVALI). Vitamin E acetate, often used as a thickening agent in the production of vape oils obtained in the illicit market, has been suggested to be a cause for EVALI.
In this application note, an LC/MS/MS method for the determination of vitamin E acetate (tocopherol acetate) in vape oil cartridges is presented. The method, which quantifies vitamin E acetate in less than three minutes utilizing a QSight® 420 triple quadrupole system, addresses the diversity and complexity of the cannabis and CBD matrix which have historically resulted in interferences that prevent rapid and accurate analysis.
Ochratoxin A (OTA) is a secondary metabolite produced by Penicillium and Aspergillus fungi species found in soil and organic matter, and is one of the most widely reported of the nearly 400 recognized mycotoxin contaminants of agricultural products. OTA can enter the human food chain through contaminated feed, primarily cereal-based, that is ingested by animals that are farmed for human consumption. OTA can also be found in wine owing to contamination of grapes by some species of Aspergillus, in particular, the strains of A. carbonarius and A. niger.
In this work, a rapid and sensitive analytical method for the determination of the extent to which OTA residues contaminate wine is presented. Utilizing a QSight 220 with both ESI and APCI ionization sources, OTA is detected and quantified in both red and white wine samples at two concentration levels - 0.5 and 2 µg/L.
