Are you looking for ways to up the ante on your LC-MS/MS when it comes to food testing? Researchers here have developed a method for the analysis of approximately 400 pesticides in food samples, and their work is available for viewing in this year’s compendium. This application note is just one of 16 you will find under Pesticides >
Using your QTRAP® LC-MS/MS System at its Full Potential OverviewUsing MRM mode, the QTRAP® 6500 LC-MS/MS was used to quantify hundreds of pesticides in food samples with high selectivity and sensitivity. Identification was further confirmed using MRM ratio identification. An alternative approach for compound identification went beyond the detection of multiple fragments.
Details of ExperimentTwenty pesticides were spiked into different food samples, and diluted extracts were analyzed using two methods.
Results and ConclusionsImproved data processing using a dual injection approach with automatic quantitation, identification, and confirmation using MasterView™ and MultiQuant™ Software. Results highlight the complementary nature of MRM ratios and MS/MS full scan offering a possibility of confirmatory analysis.
In analytical laboratories, performance is not optional. Whether supporting regulated pharmaceutical workflows, high-throughput CRO operations, clinical reporting, or food and environmental testing, your mass spectrometry and capillary electrophoresis systems are critical to productivity, compliance, and scientific confidence.
Naturally occurring toxins are an unavoidable reality of today’s global food supply, and among them, alkaloids represent one of the most analytically challenging and safety‑critical compound classes. Produced by plants as natural defence mechanisms, alkaloids can unintentionally enter food through contamination, co‑harvesting, or adulteration, posing serious risks to consumer health and regulatory compliance.
Waterproof jackets. Stain-resistant shoes. Easy-clean fabrics are marketed as “performance.” Behind those everyday claims sits a class of chemicals now reshaping regulation, brand accountability, and laboratory science: PFAS.
