Head-Space Gas Chromatography
Head-Space Gas Chromatography (HS-GC)
Analysis of residual solvents (also referred to as Volatile Organic Compounds or VOCs) as well as the volatile terpene constituents of the cannabis plant can be best achieved using Gas Chromatography, with Head-Space sampling. This technique heats the sample in a sealed vial such that all of the volatile components are vaporized into the vial headspace, above the sample, from which the sample is drawn for analysis. This results in the analysis of only the volatile components of the sample, minimizing the effects due to other complex matrix components.
Additional Methodologies Include:
- Ultra-Performance Convergence Chromatography (UPC2)
- Ultra-Performance Liquid Chromatography – Mass Spec (UPLC/MS/MS)
- Head-Space Gas Chromatography (HS-GC)
- Inductively-Coupled Plasma – Mass Spec (ICP-MS)
- Most Probable Number Enumeration (MPN)
- Enzyme Linked Fluorescence Assay (ELFA)
- Immuno-Affinity Fluorometric Assay (IA)
