ASTM WK64335

    New Test Method for Multiresidue Analysis of Pesticides in Cannabis using Liquid Chromatography-Tandem Mass Spectroscopy (LC-MS/MS)

    (What is a Work Item?)

    Developed by Subcommittee: D37.03 | Committee D37 | Contact Staff Manager


    1. Scope

    This test method allows for the determination and concentration of pesticides in cannabis. The method includes pesticides that are of the most concern or are most likely to be used on cannabis (Health Canada Pesticide Active Ingredients List and Limits). The method follows the generic sequence of solvent extraction, followed by solid-phase extraction cleanup and analysis of LC-MS/MS amenable pesticides by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Spiking was performed at concentration levels over the range of 0.005 to 0.5 ppm for 85 pesticides in cannabis with the Health Canada limits of quantitation achieved for 85 pesticides.

    It will be used by Lab to support the Cannabis Industry

    The title and scope are in draft form and are under development within this ASTM Committee.
