不同前处理方式下GC-MS法分析白酒中微量成分

摘要

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
