采用气相色谱-质谱联用（GC-MS）技术进行分析,分别采用直接进样、过有机滤膜后进样和萃取后进样3种不同前处理方式,对酱香型茅台酒中微量成分进行分析,分别鉴定出41种、43种和85种微量成分。其中以环己烷萃取后进样,GC-MS共分析出44种酯类,远大于直接进样分析出的16种和过有机滤膜后进样分析出的15种。对样品进行简单的萃取前处理后再进行分析,可提高分析效率和检测的准确率,是一种检测白酒中微量成分的简便方法。

The liquor was detected by gas chromatography（GC-MS）.Three injecting ways were taken,which were injecting followed the extraction with hexamethylene,injecting after the organic milipore filter and injecting directly without any treatment.As a result,41,43 and 85 kinds of trace elements were detected quantitatively and qualitatively,separately.For the pretreatment with hexamethylene,44 kinds of esters were analyzed out,which was prior to the results of 16 kinds for the direct injection and 15 kinds for the pretreatment with the milipore filter.It is proved to be an efficient method to detect the trace elements of the liquor with the extraction pretreatment,which can improve not only the analysis efficiency,but also the accuracy.
