Residual Solvents Testing

Comprehensive analysis of residual solvents used in cannabis and hemp extraction processes. We ensure extracted products are free from harmful solvent residues.

Solvents Tested

  • Group 1 (Solvents to Avoid): Benzene, carbon tetrachloride, 1,2-dichloroethane, toluene
  • Group 2 (Less Solvent): Acetonitrile, chloroform, cyclohexane, methylene chloride
  • Group 3 (Solvents with Low Toxic Potential): Ethanol, ethyl acetate, heptane, pentane

Why Residual Solvent Testing Is Critical

  • Health and safety of consumers
  • Regulatory compliance
  • Detection of improper extraction methods
  • Quality assurance for extracts and concentrates
  • Purity verification

Extraction Method Concerns

  • Hydrocarbon extraction (butane, propane)
  • Ethanol/alcohol extraction
  • CO₂ extraction residuals
  • Non-solvent extraction methods

Analytical Methods

  • Gas Chromatography (GC)
  • Headspace analysis
  • Parts-per-million (ppm) sensitivity
  • Rapid turnaround

Sample Requirements

  • Minimum: 2-3 grams for extracts
  • 5+ grams for flower or dried material
  • Sealed containers
  • Room temperature storage
