Use of Ion-Selective Electrodes in Tobacco and Tobacco Smoke Analyses: A Review

Abstract

Ion-selective electrodes have been used for the rapid determination of many components in tobacco and tobacco smoke. The determinations of the following tobacco smoke components with ion-selective electrodes are reviewed: hydrogen sulfide with a sulfide electrode, hydrogen cyanide with a cyanide electrode, nitrogen oxides with a nitrate electrode, and ammonia with an ammonia electrode. The determination of nitrate and ammonia in tobacco is also described. Some possible applications of ion-selective electrodes are discussed, based on the electrode sensitivity and selectivity and the level of certain components in tobacco or tobacco smoke
