Residual Solvent Analysis

In order to ensure the highest quality of concentrates are being produced as well as ensuring the producer’s process is sound, residual solvent testing is a must. Chemical solvent impurities have a significant impact on the health of the end user.

Maine requires testing of ~20 solvents on all products except for dried flower, which has not been processed.
