As food supply chains become increasingly global, governments are seeking to monitor a wider range of pesticides than ever before. This requires measuring hundreds of compounds in a number of different analyses, meaning labs need multi residue processes and sample preparation techniques that are both accurate and cost-effective. Chromatography combined with mass spectrometry is ideally suited to such demands, particularly with the advent of faster and more sensitive chromatographic methods and mass specs. ChromSciences offers both established and new complimentary chemistries to separate targets from matrix, enabling labs to cover familiar matrices but also the more challenging ones. And our highly selective mass specs also provide the opportunity to dilute the matrix away whilst still achieving trace level detection. Combined LC/MS and GC/MS multi residue methods often cover the majority of compounds of interest for a given lab and ChromSciences sample preparation strategies can produce one extract suitable for both. Further the LC/MS and GC/MS platforms themselves are available, preconfigured for multi-residue screening according to methods, which have been developed and validated by ChromSciences’s expert collaborators and which our engineers can set up and check out for each new instrument installation.
