Multiresidue Pesticide Analysis for Dietary Supplements and Raw Materials

There are over 1000 pesticides with diverse molecular structures and chemical makeups. In addition to this complexity, the low target detection levels and the variability in product matrices pose a challenge for pesticide residue analysis. The current best practice for analysis is a multiclass/multi-residue pesticide method using both GC-MS/MS and LC-MS/MS for the analysis of a wide range of compounds. Single-class/single residue methods also exist for certain pesticides that require special analytical preparation or chromatographic conditions.

Specifically for dietary supplements, and their ingredients, we offer pesticide residue analysis that is in accordance with USP <561>. USP <561>, Articles of Botanical Origin, lists selected priority pesticides along with maximum limits. For botanical extracts, the limits are adjusted according to the limits listed in USP <565>. The majority of the pesticides listed in USP <561> are analyzed by GC-MS/MS and LC-MS/MS. However, inorganic bromide and dithiocarbamates are tested with single residue methods.
