Recent regulations on food analysis require screening for pesticides using confirmatory techniques, such as GC-MS and LC-MS/MS. More than 1000 pesticides are used worldwide and, along with their metabolites and degradation products, are present in food. There is a demand for powerful and rapid analytical methods that can identify pesticides with high confidence in a broad range of food matrices and quantify at low concentrations with good accuracy and reproducibility. Challenges for pesticide residue laboratories at the moment are the request to test for more compounds, in a wider range of samples, all without sacrificing data quality. The QTRAP® 6500 LC-MS/MS system uses multi-component IonDrive™ technology to:
In addition, the QTRAP 6500 system uses the patented and proven Linear Accelerator™ trap technology to:
A new method for the quantitation and identification of hundreds of pesticides in food samples was developed and successfully applied to the analysis of complex food samples using the QTRAP 6500 system. Results are compared to QTRAP 5500 data. The increased sensitivity was used to extensively dilute sample extracts to eliminate ion suppression caused by matrix components and the extended linear dynamic range allowed quantifying more pesticides across a wider range of chemical properties. QTRAP scanning was used to investigate the presence of matrix components and to identify targets with high confidence through library searching. Quantitative and qualitative results were generated using MultiQuant™ and LibraryView™ Software.

In a recent webinar, which is now available on-demand, Holly Lee powerful strategies to tackle complex residue testing. From boosting throughput to fine-tuning method sensitivity, Holly shared key ways to maximize performance across large pesticide panels.
Whether we are raising glasses of rosé in a vineyard in France or enjoying a lager in a casual street restaurant in China, it is likely that the last thing on many people’s minds is the chemical risks from their beverage. Unless you work in food science, then it might actually be the first thing.
As PFAS regulations tighten globally, laboratory managers are navigating a complex economic landscape. Whether operating in a commercial or non- commercial setting, the pressure to deliver accurate, defensible, and timely PFAS data is mounting. At SCIEX we understand that the right technology can turn this regulatory challenge into a strategic opportunity.
