GC-MS

Residual solvents, terpenes and headspace analysis.

Gas chromatography-mass spectrometry reveals volatile substances invisible to HPLC. We use it to quantify residual solvents (ICH Q3C) and to identify complex terpene / process residue mixtures.

Capabilities

What we measure

  • Residual solvents per ICH Q3C (benzene, methanol, hexane, toluene...)
  • Terpenes and terpenoids (60+ compound profile)
  • Pesticide residues (GC-MS/MS, Ph. Eur. 2.8.13)
  • Volatile organic compounds (VOC)
  • Monomer residues (styrene, vinyl chloride)
  • Odour analysis (headspace, SPME)
  • Fatty acid methyl esters (FAME)
Sample types
Oils (cosmetic, food, pharmaceutical)Extracts (cannabis, herbs, resins)Synthetic API materialsFinished products (solutions, injectables)Packaging (plastic migration)Fragrances, perfumes
Sample preparation

2–10 ml / g sample in sealed container. For headspace we accept 20 ml vials. Do not open before shipping — volatiles escape.

02 Q
  • 01

    Can you detect Class 1 (carcinogenic) solvents?

    Yes. Benzene, 1,2-dichloroethylene, 1,1-dichloroethane and CCl₄ quantified below ICH Q3C limits (typically 2 ppm). Report always includes compliance assessment.

  • 02

    Terpene analysis — how many compounds?

    Standard: 42-terpene profile (mono- and sesqui-). Extendable to 60+ on request. For cannabis we run comprehensive panel aligned with US testing standards.
