Our U.S. Food and Drug Administration (FDA) Multi-Residue Analysis employs the methodology used for surveillance testing, as listed in the FDA Pesticide Analytical Manual (PAM) Vol. 1, Section 203E. Five major classes of pesticides are detected utilizing this screen, including Organophosphates, Organonitrogens, Organochlorines, Pyrethroids, and Carbamates. Single classes and custom testing packages are also available using this method. While particularly suitable for testing imported products, our FDA screen is appropriate for routine surveillance testing as it covers most common pesticides, and many that are now banned but highly persistent in the environment.

NOP Screen

Our NOP Screen covers the most common pesticides found on the FDA screen, but also incorporates many of the newer and widely used pesticides targeted by the U.S. National Organic Program (NOP) that are not detectable by traditional screens. We utilize the Quechers extraction method in combination with LC-MSMS and GC-MSMS analyses for a highly sensitive and comprehensive package. With sensitivity as low as 0.01 ppm and the ability to detect most newer pesticides, the NOP screen is ideal for demonstrating MRL compliance for any country of destination, organic validation, satisfaction of audit requirements, and surveillance testing.
