摘要
以 SKALAR SA2 0 0 0 /40 0 0流动注射分析仪为研究对象 ,尝试运用该仪器检测烟草中的几种化学成分 ,考察了检测结果的准确性和重现性。摸索出该分析仪较适合实际工作要求的操作条件 。
The use of the Skalar SA2000/4000 segmented flow injection analyzer in the determination of several chemical components (e.g. total sugar content, total nitrogen content and nicotine content) in tobacco is reported in this paper. The optimum conditions for sample treatment and for the methods used in the determinations are studied. The accuracy and reproducibility of the analyzer are tested by using a standard reference material (GBW 08514). As proved by experimental results, the FI Analyzer showed its significant features of high speed in analysis, and of more accurate and reproducible results obtainable as compared with the conventional methods. Based on authors′ study, a more rational operation instruction is proposed to be used in routine analysis, and the validity of the FI Analyzer is verified, and it is especially suitable for batch analysis.
