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.
Trifluoroacetic acid (TFA) is emerging as one of the most concerning ultrashort-chain PFAS in Europe’s food supply – particularly in cereals, a staple consumed daily by millions. A report from PAN Europe reveals a widespread and largely unmonitored contamination trend that raises serious questions about food safety, regulatory blind spots, and future monitoring strategies.
PFAS analysis is complex, but expert guidance doesn’t have to be. In this episode of our ‘Ask the PFAS expert series’, we’re joined by Michael Scherer, Application Lead for Food and Environmental, to answer the most pressing questions in PFAS analysis. From why LC-MS/MS systems are the gold standard for analyzing diverse PFAS compounds, to which EU methods deliver reliable results for drinking water, and to practical steps to prevent contamination, Michael shares actionable insights to help laboratories achieve accuracy, consistency, and confidence in their workflows.
During an LC-MS/MS experiment, traditional fragmentation techniques like collision-induced dissociation (CID) have long been the gold standard. Electron-activated dissociation (EAD) is emerging as a transformative tool that enhances structural elucidation, particularly for complex or labile metabolites.
