Residual Solvents

Residual solvents are leftover chemicals from the process used to extract cannabinoids and terpenes from the
plant. The solvents are evaporated to prepare high-concentration oils and waxes. Sometimes, the evaporation
process does not remove all of the solvent. Since these solvents are not safe for human consumption, it is
important to verify their absence so you can guarantee you are providing a safe, chemical-free product.
The Shimadzu GCMS-QP2020 NX with HS-20 Headspace Sampler enables rapid identification and quantitation of
very low concentrations of residual solvents. However, if one plans to purchase the GCMS-TQ8050 NX or GC-
2030 with headspace for terpene profiling (page 8) or the GCMS-TQ8050 NX for pesticide analysis (page 9), then
any one of these platforms is capable of measuring residual solvents analysis but will provide different levels of
identification confirmation.
