摘要
气相色谱仪器是分析白酒中微量成分的重要设备,分为填充柱气相色谱仪和毛细柱气相色谱仪。气相色谱仪器的控温精度、酒样进入汽化室汽化后进入色谱柱的方式、DNP色谱柱效、酒样分析时间的长短等都是影响气相色谱仪分析白酒中微量成分数据准确性的重要因素。
Gas chromatograph is the important apparatus to analyze microconstituents in liquor and it is classified into packed column gas chromatograph and capillary column gas chromatograph. The temperature-control accuracy of gas chromatograph, mode of entry of liquor samples from vaporizing chamber after vaporization to chromatographic column, DNP chromatographic column efficiency, and liquor analysis time length etc. are the factors influencing the accuracy of the data in the analysis of liquor microconstituents by gas chromatograph. （Tran. by YUE Yang）
