Cannabis Adulterants - Inhalable Concentrates

Method Description

The determination of Vitamin E and Medium Chain Triglycerides (MCTs) in cannabis extracts using Gas Chromatography coupled with Triple Quadrupole Mass Spectrometry (GC-TQ) is a highly sensitive analytical method. Sample preparation begins with dissolving the cannabis extract in an organic solvent to extract the lipid components, including Vitamin E and MCTs. The prepared sample is injected into the GC system, where it is vaporized and passed through a capillary column. This column separates Vitamin E and MCTs from other components based on their volatility. The Triple Quadrupole Mass Spectrometer (TQ-MS) then identifies and quantifies these analytes through multiple reaction monitoring (MRM), providing high specificity. This method allows for accurate detection of lipid additives like Vitamin E acetate, which is important for assessing product safety and quality in cannabis extracts.
