Pesticide testing for cannabis is a critical process that helps ensure the safety of cannabis products for consumption. The testing process involves several steps, which include:
Sample Intake and Identification: PPB Analytical Incorporated receives the cannabis samples for testing and verifies the identification and chain of custody for each sample.
Sample Preparation: The cannabis sample is prepared by grinding it to create a representative sample. This homogenized sample is then weighed and placed in a test tube.
Extraction: The homogenized cannabis sample is extracted with a solvent to extract the pesticide residues. The extracted solution is then filtered to remove any impurities.
Clean-up: The filtered extract is subjected to a clean-up process to remove any interferences and improve the detection limit of the method set by Health Canada.
Analysis: The clean extract is analyzed using a combination of a GC-MS and LC-MS to identify and quantify pesticide residues.
Data Analysis and Interpretation: The data is then analyzed, and the results are compared to regulatory standards set by Health Canada. Based on these same standards, PPB Analytical will determine if the sample passes or fails.
Reporting: PPB Analytical Incorporated will then generate a report detailing the methods used, the results obtained, and any relevant interpretations or conclusions. The report is typically provided to the client along with a Certificate of Analysis.
