Objectives: Nicotine lactate, nicotine tartrate, nicotine benzoate and freebase nicotine (FBN) are four forms of nicotine delivery systems presented or used in tobacco products, for example, e-liquids for electronic cigarettes. So, compare their...

Aromatic aldehydes (furfural, benzaldehyde, cinnamaldehyde, ethyl vanillin, and vanillin) are of interest for e-vapor products testing based on recent guidance from FDA‐CTP. There are limited reports of direct application methods that include each of...

Glycidol is of interest for e-vapor products testing based on guidance from FDA-CTP. Some recently reported methods involve direct-inject sample preparation followed by GC-MS analysis with limited sensitivity and selectivity. Other methods offer good...

At the 2021 CORESTA Smoke-Techno Conference, we presented a novel method for the quantitation of four organic acids (formic acid, acetic acid, propionic acid and lactic acid) by ion chromatography in e-vapor products. Herein, and following from that...

Organic acids (formic acid, acetic acid, propionic acid and lactic acid) are of interest for e-vapor products testing, especially propionic acid which is included in guidance from US Food and Drug Administration Center for Tobacco Products (FDA-CTP)....

In 2019 at the TSRC, we presented a quicker and robust method using a Dionex CS18 column for the analysis of ammonia in e-cigarette aerosols and e-liquids by ion chromatography. The method has a short run time of 13 minutes (including equilibrating...

Organic acetates (methyl acetate, ethyl acetate, isobutyl acetate, isoamyl acetate and benzyl acetate) are flavorants and are of interest for E-vapor products testing based on recent guidance from FDA-CTP. A review of the literature shows few, if...

Nicotine is a key component in many e-cigarette formulations and during the vaping process, nicotine exists in both the gaseous phase and aerosol phase. There are two type of vaping techniques- mouth-to lung (MTL) and direct-to-lung (DTL). The...
