The required sample size for residual solvent analysis is dependent on the size of your production batch per 4-110 – Regulated Marijuana Testing Program: Sampling Procedures.


Marijuana is a complex natural product with hundreds of compounds that can cause chromatographic interference in the analysis of residual solvents. Accurately quantifying solvents can prove to be challenging unless you have the right methodology and equipment. The answer is Gas Chromatography with Mass Spectrometry (GC/MS). Testing for residual solvents with GC/MS identifies the molecular “fingerprint” of each solvent and gives Agricor Laboratories the most defendable data in cannabis testing.

Having the right equipment is critical, but it is only one piece of the Agricor Validated Laboratory System. Our lab is the ONLY cannabis testing facility set to the same standards of a Pharmaceutical Laboratory. By following Good Laboratory Practices (GLP) we deliver the most accurate results in the industry.
