Improved Screening for 250 Pesticides in Matrix using a LC-Triple Quadrupole Mass Spectrometer

Instrument Type: LCMSMS

Both food safety and environmental regulatory requirements are demanding greater sensitivity on an increasing number of analytes in an increasing number of matrices. To meet these requirements, it is necessary to analyze a large number of analytes quickly at low levels. Triple quadrupole mass spectrometers are the industry standard for fast and reliable analysis achieved through the selected reaction monitoring experiment (SRM). We utilize a triple quadrupole MS equipped with a new Q2 collision cell enabling the rapid analysis of 250 pesticides in a screening application.

Use of UHPLC and High-Resolution MS for Quantitative Analysis of Pesticides in Onion Matrix

Instrument Type: LCMS

Monitoring for pesticide and other chemical residues in produce is essential to maintaining a safe food supply. Monitoring is typically done by public agencies, but budget restrictions have increased pressure on these agencies to improve productivity while lowering costs. We demonstrate the ability of a high-resolution, accurate-mass UHPLC-MS system, combined with appropriate application-specific workflow software, to provide fast, confident, and precise screening and quantitative analysis of pesticides in onion matrix.
