中国白酒中含有大量的香味成分和滋味成分，其中很多物质的含量极其稀少，这就给这些物质的分析工作造成了很大的困难。通常情况下为了分析这些极微量的物质，人们需要对白酒样品进行浓缩前处理，然后再利用气相色谱对浓缩样品进行分析。样品的浓缩过程是一项非常耗时耗力的工作，并且浓缩样品中含有大量的溶剂，这些物质在色谱分析中可能引起严重的分析误差，损坏色谱柱或者检测器。而大体积进样技术（LVI）则有效地避免了这些缺点。大体积进样技术可以在短时间内对分析样品进行浓缩，并且排除掉绝大多数的溶剂，从而大大提高了分析的灵敏度。将大体积进样技术和质谱分析技术联合应用，可以大大提高对白酒中极微量成分分析工作的准确性。

Contains the flavor and taste a lot of Chinese liquor, the content of many material extremely scarce, caused great difficulties to the analysis of these substances. Normally in order to analyze the trace substance, people need to liquor samples were concentrated before treatment, and then using gas chromatography to concentrated samples analysis. The enrichment process samples is very time consuming work, and contains a lot of solvent concentration in the sample, these substances may cause serious error analysis in chromatography column, damaged or detector. While large volume injection (LVI) technology can effectively avoid these shortcomings. Large volume injection can be concentrated on the analysis of samples in a short time, and eliminate most of the solvent, thereby greatly improving the analytical sensitivity. The large volume injection technology and mass spectrometry combined with accuracy, can trace component analysis work is greatly improved in liquor.
