%X A new ion chromatographic method was developed for the quantitative determination of ammonia and potassium in tobacco The tobacco samples were treated with dilute nitric acid and K , NH 4 were extracted The method is fast and convenient. The relationships between peak heights and initial concentrations of K and NH 4 were linear. The detection limits were 0 05 mg/L for K and 0 03 mg/L for NH 4 . Recoveries of K and NH 4 were 96 7% 106 7% and 96 5% 109 1% respectively. The whole procedure of determination can be completed within 5 min
