Mitigate Matrix Interference With New Isotopically Labeled Pesticide Residue Internal Standards From Restek

pesticide_standard_prAny food safety chemist can attest that interference is a major concern when performing pesticide residue analysis. But with the release of its expanded line of internal and surrogate reference standards, Restek now offers enough options to mitigate interference in nearly any matrix!

Isotopically labeled to provide the best approach for pesticide residue quantification, these new internal standards are economically priced and compatible with both LC-MS and GC-MS applications. They are even useful for optimizing LC-MS/MS system performance. Like all of the certified reference materials (CRMs) manufactured and QC-tested in Restek’s ISO-accredited labs, they can also help you satisfy your ISO requirements with ease.
