Headspace GC/MS detection of all California-regulated residual solvents in cannabis concentrates and extracted products — verified before distribution.
Extraction solvents play a necessary role in concentrate production — but they must be thoroughly removed before a product is safe for consumption. Even trace amounts of butane, propane, ethanol, or other solvents left behind after processing can exceed California DCC action limits and compromise consumer safety.
Our laboratory uses validated headspace GC/MS methods to detect solvents at low ppm levels. Results are reviewed carefully against individual compound thresholds, and we communicate directly with your team if a reading approaches regulatory limits or shifts unexpectedly from previous batches.
Headspace Gas Chromatography/Mass Spectrometry heats the sample to volatilize residual solvents, then injects the vapor into the GC/MS instrument. This approach minimizes sample matrix interference and provides accurate quantification of volatile compounds at ppm sensitivity.
Incomplete purging, inconsistent temperature control, shortened processing cycles, and equipment variability are the most common causes. Reviewing extraction parameters often reveals where process adjustments are needed before the next production run.
Yes. Differences in vacuum strength, heat distribution, or equipment maintenance can directly influence solvent retention levels. Even small mechanical inconsistencies can produce measurable differences in analytical results.
Modern headspace GC/MS can detect residual solvents at very low concentrations — often well below California regulatory thresholds. This sensitivity allows manufacturers to identify process trends early and correct variability before it becomes a compliance issue.
Absolutely. Historical trending reveals gradual shifts in extraction efficiency that may not be immediately obvious. Consistent tracking prevents unexpected failures by catching subtle process changes before they cross action limits.
Review individual solvent concentrations relative to their specific action limits, detection threshold values, and any unusual variation compared to previous batches. That context helps inform production decisions and process improvements.
