Residual Solvents

Overview

Solvents are used in the production of concentrated cannabis products. Even trace amounts of these solvents can have adverse health effects and must be removed at the end of the extraction process.

Analysis is performed using Head-Space Gas Chromatography with Mass Spectrometric detection (HS-GC/MS). All results are quantitated against calibration curves prepared from certified reference standards.
