Leveraging ESI and APCI LC/MS Techniques to Meet the Most Demanding Global Cannabis & Hemp Pesticide Testing Requirements

A new analytical LC-MS/MS method has been developed and validated to allow cannabis laboratories to complete the entire Pesticide assay (including all the California and Canadian list pesticides) in one quick method, using one instrument. Data will be presented to show the long-term stability of the method, the simplicity of sample preparation and techniques to overcome matrix effects, robustness towards any contamination from the dirty matrices from cannabis extracts, and detection limits well below the State requirements (LOQ<=10 ppb).

References will show that having a validated method and SOP for the cannabis testing industry is key in ensuring the highest quality of cannabis reaches the patient. In addition, the influences of the various cannabis sample types tested will be discussed, and details specified on how to handle flower, concentrates, and edibles.
