Qualitative Pesticide Screening for Monitoring Environmental Samples

UNIFI Scientific Information System is Waters' next generation informatics platform and the first software solution to merge LC and high performance MS, data management and laboratory workflow into one single solution.

Multi-analyte screening methodologies are essential for monitoring food and environmental samples across the globe. The goal of these methods is to eliminate the compliant samples and to identify the non-compliant samples for subsequent confirmation and quantification. Sensitivity must be in line with the relevant regulatory limits for residues in complex matrices. Also, a method must be validated in accordance with legislative requirements. This method would ideally be rapid, cost effective and a streamlined process, from sample preparation to reporting results.

Many laboratories are progressing towards high-resolution mass spectrometry (HRMS) screening techniques that, in theory, can monitor for an unlimited number of targets at the same time as providing information to help discover unknown compounds or metabolites of interest.

This application note introduces a novel way users can customise data review within the UNIFI Scientific Information System in a routine environment.

In this short video, Waters Principal Scientist Gareth Cleland explains how explains how High Resolution Mass Spectrometry, or HRMS, and integrated informatics (UNIFI) can be used for more effective environmental screening.
