摘要：The present invention discloses a method for quick and simultaneous

determination of 16 inorganic anions and organic acids in tobacco by ion chromatographyThe retention behavior of inorganic anions and organic acids on the anion exchangecolumn was investigated using potassium hydroxide produced by EGC-II KOH eluentautogenerator as eluent. The optimized gradient elution condition was obtained. Thesamples were prepared through extraction, filtration and dilution before analysis. Theseparation was performed on an anion exchange column. The time of the gradient elutionprogram was 50 mins. Under the optimized conditions, the calibration of peak area for allthe analytes were linear in the ranges of 10. The method in the present invention has theadvantages of simplicity, rapidity and accuracy, and is able to simultaneously determine16 inorganic anions and organic acids in tobacco by one single time of injection.
