QSight Triple Quad 200 Series

Changing the source on many an LC/MS/MS instrument from ESI to APCI, and vice versa, involves cooling the source, manual removal and installation of the new source, followed by heating of the new source to the operating temperature, resulting in low throughput for analyses utilizing both ESI and APCI sources. Conversely, the PerkinElmer QSight LC/MS/MS features a dual ESI and APCI source, allowing for the collection of data in two complementary modes, thus maximizing output from a single injection. This study demonstrates that the QSight 220, with its dual independent sources capable of measuring in both ESI and APCI modes, can cover different classes of compounds with lower limits of quantitation, even in a complex matrix.

Mycotoxins are toxic secondary metabolites produced by various fungal species growing in foods and animal feeds. To minimize risk and protect consumers, mycotoxin levels in foods and/or feeds have been regulated by agencies in many countries around the world. A number of analytical methods for the determination of mycotoxins have been utilized in the past, however LC/MS/MS method has become the method of choice for quantification and confirmation of mycotoxins in various food sample matrices owing to its superior sensitivity, selectivity and capability of analyzing multiple target mycotoxins in a single run.

In this application note, a method for the analysis of 12 mycotoxins in a number of common food matrices (yellow corn, white corn, wheat, soybean, almond, oat breakfast cereal, and peanut butter) utilizing a QSight 220 LC/MS is presented. A stable isotope dilution assay (SIDA) technique is used, which has been proven to be the most effective and preferred calibration approach for mycotoxin analysis in complex sample matrices because it can not only compensate for sample matrix effects, but also minimize variations in analytical procedures.

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.

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.

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.

Fipronil is a broad-spectrum phenylpyrazole insecticide almost used to protect corps from insects but also to treat lice and ticks in chickens. The U.S. EPA classified fipronil as Group C, possible human carcinogen, therefore International organizations defined admissible limits for the fipronil usage which in egg is of 5 µg/L4. LC-MS/MS technology can provide a robust and reliable method to detect such a contaminant in food.

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.

Nitrosamines are a well-known group of highly potent, mutagenic impurities formed by the reaction of secondary amines with nitrite under acidic conditions. The most probable nitrosamine impurities are NDMA, NDEA, NMBA, NDBA, NDIPA, NEIPA. Following the initial observance of nitrosamine impurities in sartan drugs used to treat high blood pressure and congestive heart failure in 2018, acceptable daily intake levels of 96 ng/day for NDMA and NMBA, and 26.5 ng/day for NDEA, NDBA, NDIPA and NEIPA have been adopted by most of the regulatory bodies.

This application note describes an efficient, sensitive and reproducible method developed using the PerkinElmer QSight 220^® LC/MS/MS for the detection and quantification of NDMA, NDEA, NMBA, NDBA, NDIPA and NEIPA impurities in sartan and metformin active pharmaceutical ingredients (APIs).

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.

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.

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.

Wine can often contain pesticides and fungicides that have been sprayed on the fruits during their growing period. In addition to these contaminants, wine can also contain additives that have been deliberately added during production processes to improve its flavor and color. In this study, a simple and sensitive LC-MS/MS method has been developed and applied for the determination of both pesticides and pigments in a single analytical run.
