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.

For more than 20 years, the CDCO has supported academic, commercial, and not‑for‑profit drug discovery programs with deep expertise in pharmaceutical lead optimization. Within the bioanalytical group, their role is to enable rapid and reliable decision‑making through quantitative analysis of candidate drugs in biological matrices.
PFAS are increasingly at the center of regulatory change, scientific research, and industry discussion worldwide. As analytical capabilities improve and expectations around environmental responsibility continue to evolve, understanding the role PFAS play, and how they are being addressed, has never been more important. This blog provides an overview of what PFAS are, why they matter, and how responses from regulators and industry are changing.
Pesticides are widely used in agriculture to protect crops and maintain yield, but their presence in food must be carefully monitored. To safeguard consumers, regulatory authorities worldwide set maximum residue limits (MRLs), often at very low concentrations and across a wide range of compound classes.
