白酒中微量芳香成分的气相色谱-质谱检测

The Analysis for Microconstituents in Chinese Spirit by Gas Chromatograph/Mass Spectrometry (GC/MS)

分别采用DB-WAX、HP-5MS石英毛细管柱,选用直接进样方式,利用气相色谱-质谱联用仪对重庆某白酒厂4种白酒中的微量成分进行定性分析,通过图谱库检索,鉴定出4种白酒中微量芳香物质的成分,并研究了其在不同白酒中的差异.本方法为白酒的勾兑和质量控制提供了一种高效、准确的分析方法.

Four chinese spirits were qualitatively analyzed by gas chromatograph/mass spectrometry （GC/MS） using HP-5MS and DB-WAX columns. The most kinds of trace elements had been identified via database retrieval and the difference of micro-constituents in these spirits was detected. The method provides an efficiency and accuracy technique for chinese spirits blending and quality control.
