Pesticide analysis in Hops and Cannabis by GC-MS-MS

The rising popularity of medical and recreational cannabis has dramatically increased the demand for this plant. Cultivators of the closely related hops plant and cannabis may use pesticides or other chemical residues to protect their plants from mold and insects, however few of these substances may be legally used in cannabis. The possible adverse health effects of unapproved chemicals have drawn significant public attention. Many chemical residues may be measured using LC-MS however GC-MS is also needed for some compounds. In this work we used GC-MS-MS with a modified QuEChERS extraction and cleanup to rapidly measure pesticides in hops and cannabis with high performance.
