Abstract
With the rise in popularity of e-cigarettes or ‘vaping,’ especially among young people believing the practice to be harmless, more information is needed to better inform the public in their decision-making regarding the activity. In this work, we describe the analysis of electronically-produced vapors of commercially available nicotine-vaporization liquids and variable voltage vaporizers for carbonyl byproducts by liquid chromatography. Carbonyls have been collected by dinitrophenylhydrazine (DNPH) derivatization and desorption with acetonitrile. Analyses have been performed on a novel, inexpensive liquid chromatography system utilizing both UV and stop-flow Raman detection. Carbonyls have been effectively separated and detected using the novel method. The system has been chosen for its ease of use and appropriateness for an educational setting.
