Pesticide residue screening is a pre-sale requirement for all states which have legalized the recreational or adult use of cannabis and cannabis related products.  In the absence of guidance at the federal level, individual states are establishing testing requirements for residues to be monitored as well as setting “action” levels.   Consensus testing methods are not currently available, which leaves laboratories free to develop extraction and analysis methods that may only meet the requirements of a single state.  

With no product labels or Maximum Residue Levels (MRL’s) in place, a comprehensive approach to pesticide residue testing gives a more complete picture of industry pesticide practices using the model currently used for conventional agricultural commodities.  

In this webinar presentation you will learn how Pacific Agricultural Laboratory has developed and validated a workflow for residue analysis in cannabis and industrial hemp utilizing both GC-MS/MS and LC-MS/MS with straightforward solid phase extraction (SPE).  The use of two MS/MS platforms allows the laboratory to optimize both chromatography and detector response for over 200 active ingredients prohibited for use.  Data generated using this workflow will show acceptable recoveries for the target compounds, with limits of quantitation of 0.1 mg/kg for approximately 90% of the target list.

Learning Objectives:

• How to optimize your analysis for over 200 active ingredients that are prohibited for use on cannabis and industrial hemp
• Understanding pesticide residue screening workflows using both GC/MS/MS and LC/MS/MS
