CMT’s residual solvent analysis is performed using Gas Chromatography (GC).
Residual Solvent testing is required for all solvent-based concentrate production until the production process has been validated (4 batches, at least 6 days apart). Please always check with your MED agent to confirm process validation.
Per Colorado law, the following are the solvents and their limits:
- Butanes <5000 ppm
- Heptanes <5000 ppm
- Benzene <2 ppm
- Toulene <890 ppm
- Hexane <290 ppm
- Total Xylenes <2170 ppm
After production process validation, residual solvent testing will be done on a random-sampled basis by the MED.
