Free-Base Nicotine Determination in Electronic Cigarette Liquids by (1)H NMR Spectroscopy
[Image: see text] E-liquids usually contain significant nicotine, which will exist primarily in two forms, monoprotonated and free-base, the proportions of which are alterable through the effective pH of the medium. The fraction of nicotine in the free-base form is α(fb), with 0 ≤ α(fb) ≤ 1. When do...
