Residual solvent testing & regulatory compliance

Our laboratory provides high-sensitivity analytical testing to ensure the safety, purity, and compliance of cannabis products. We utilise pharmaceutical-grade standards and a suite of specialised methods to detect organic volatile impurities that may remain after the extraction and manufacturing processes.

Pharmacopeial compliance: USP <467>

We align our testing protocols with USP <467> Residual Solvents, the global benchmark for pharmaceutical safety. This ensures your products meet international standards for medical and consumer safety. 

  • Methodology: Analysis performed via Headspace GC-MS/FID (Gas Chromatography).
  • Procedures: Standardised screening following USP Procedure A for identification and limit testing.
  • Customisation: We offer a custom Eurofins Food & Feed Testing list based on USP <467> to target specific Class 1, 2, or 3 solvents relevant to your unique formulation.
