Pesticide Testing

We offer two reporting formats, if the sample is a WA state compliance sample, we will include the 59 compounds listed in WAC 314-55-108 on the COA.  If the sample is an R&D sample, we will report 126 compounds.  If you would like the additional compounds reported out on a compliance sample, we will include the additional compounds on a separate test.  

When sending compliance samples, simply choose the correct I-502 panel for your matrix and the pesticide test will be included.  If you’d like the additional pesticides reported, you’ll add on the “Additional Pesticides” test/assay.  When sending an R&D sample, choose the R&D test/assay.

In order to achieve accurate quantitation of pesticide residues, we use both a GC-MS/MS and LC-MS/MS to detect over 120 compounds. We do a matrix-matched spike for each batch to ensure the complicated behavior of cannabis flower and concentrates can be better accounted for. We are constantly investigating new compounds and improving our chemistry to offer the most comprehensive and transparent testing in the state. Our staff has years of experience and are often able to work with clients on specific compounds of concern and other matrices such as soil or air filters from facilities to isolate sources of contamination.
