The Anatomy and Chemistry of a Disposable Vape

In this case study, readers learn how advanced analytical techniques can be used to uncover what is really inside a disposable vape. By combining 2D X-ray imaging, GC–MS, and ICP–MS, the study reveals both the internal structure of these devices and the chemical and elemental species associated with their use. Readers are guided through the anatomy of the vape, the role of key internal components in aerosol generation, the identification of major formulation ingredients such as nicotine, carrier solvents, and cooling agents, and the detection of trace metals that may raise follow-up questions about material sources and exposure. The case study shows how a multi-method approach can move the discussion beyond branding and assumptions, offering a measurable, evidence-based picture of how disposable vapes are built and what they may deliver.
