Residual Solvents

Residual solvents are the chemicals that remain in plant material after extraction. Since each extraction process is unique, they yield different results based on factors like pressure, temperature, the profile of the solvent itself, and soak time.

To ensure that all residual solvents effectively are not present in finished products, we carry a collection of certified residual solvent testing standards for use with GC-MS testing methods. 

A Certificate of Analysis (COA) is shipped with every residual solvents standard.
