Cartridges containing cannabis extract or CBD are some of the cannabis industry’s fastest-growing major product categories. It is imperative that the composition of these products is understood to ensure that components in the product do not contribute to e-cigarette or vaping product use-associated lung injury (EVALI). Vitamin E acetate, often used as a thickening agent in the production of vape oils obtained in the illicit market, has been suggested to be a cause for EVALI.
In this application note, an LC/MS/MS method for the determination of vitamin E acetate (tocopherol acetate) in vape oil cartridges is presented. The method, which quantifies vitamin E acetate in less than three minutes utilizing a QSight® 420 triple quadrupole system, addresses the diversity and complexity of the cannabis and CBD matrix which have historically resulted in interferences that prevent rapid and accurate analysis.
