Residual Solvents Testing

Accelerated Labs has developed and validated a residual solvent analysis to identify the presence of harmful solvents, impurities, and/or chemicals present in concentrated or formulated forms of Cannabis oil/extracts. In addition to this, we can offer the FDA’s accepted Residual solvents tests USP <467> for those customers who need a compendial analysis. Our residual solvent analysis employs HSGC/MS to identify solvents and trace residues of chemicals from the extraction process.
