Abstract

Electronic cigarette liquid (e-liquid) often degrades during vaporization in electronic cigarettes via a number of pathways, including dehydration reactions. The amount of water present in e-liquid may influence the number and amount of degradation products formed during the vaporization process. In order to allow a subsequent test of this hypothesis, a method was developed for the quantification of water in e-liquid by way of nuclear magnetic resonance spectroscopy (NMR) peak integration. The method was verified using standard addition, and was found to have a range of accuracy and precision from 0.361 to 0.619 and 0.127 and 0.474 mole-percent respectively (N=9).
