Application Note: Optimization of Sample Preparation for Pesticide Analysis in Oil-Based Cannabis Products using LipiFiltr
26 September 2019

This application note outlines the performance benefits achieved using the LipiFiltr® cleanup cartridge for the analysis of pesticides in oil-based cannabis products using LC-MS/MS analysis. The pesticides evaluated in this study include those listed in the Oregon monitoring list (≈60 pesticides). CBD oil was used as the representative matrix. A comparison of pre- and post-LipiFiltr® cleanup using full scan GC-MS is also presented to demonstrate the removal of lipid coextractives. This work was originally presented as a poster at the North American Chemical Residue Workshop (NACRW) 2018 in Naples, Florida.
