Improvement of Continuous Flow Analyzer Method for Determination of Ammonia in Tobacco

In order to quickly determinate ammonia content in tobacco, we used dichloroisocyanuric acid sodium salt to replace sodium hypochlorite in continuous flow analyzer method for tobacco ammonia determination, which is an industrial standard method. The results showed the method had good reproducibility and accuracy, the variation coefficient was less than 3% and the recovery ratio was 98.83%-101.97%. There was not significant difference between our method and industry standard method.
