气相色谱法测定白酒中乙醇的含量(1).pdf

安顺学院10化本班毕业论文摘要普通的白酒中通常会有40%—50%的乙醇，随着酒业的发展，酿酒的工厂也相应建立起来，也有很多是私人的小酒坊。但是，有些人为了谋取暴利，没有按照正常的酿造工艺来酿酒；而是用勾兑的方式添加工业酒精或是甲醇来充当正常的白酒，然后向外出售。这样的酒严重危害了人们的健康。我们利用气相色谱分析法可以很快地对白酒中乙醇的含量进行测定而且简便。关键词:气相色谱白酒乙醇测定ABSTRACTOrdinaryliquorusuallycontains40%—50%ethylalcohol，withthewineindustrydevelopment.themakewinefactrywiththedevelopmentoneafteranotheraresetup.manypeoplewillhavetheyprivatedfactory,howevery,somepeoplewanttomademoremonely,theymadetitfortherightmeasure,orputtousethemannfacturespiritandwoodalcohol.than,selltoothergood.thisethylalcoholisseriousedthepeoplehealthed.weusuallytheairposturecolourspectrumanalyseit.thismeanssimpleandconvenient.Keyword:airposturecolourspectrumwhitespiritenthyalcolohassay1安顺学院10化本班毕业论文目录引言......................................................11.气相色谱的简介..........................................11.1.色谱法的分类............................................11.2.气相色谱仪的结构........................................11.3.气相色谱仪的使用原理....................................22.实验目的................................................43.实验原理................................................44.实验仪器与药品..........................................45.实验步骤................................................55.1实验样品的准确..........................................55.1.1内标样...........................................55.2色谱条件的设定..........................................55.3气相色谱仪的操作........................................55.4样品分析................................................55.4.1校正因子的测量......................................55.4.2对正内标样进行色谱分析..............................65.4.3对内标样进行色谱分析................................65.4.4对白酒样进行分析....................................65.4.5关于色谱峰的定性....................................62安顺学院10化本班毕业论文.5.5实验数据处理............................................66.结束语................................................7参考文献...............................................8致谢词.................................................93安顺学院10化本班毕业论文引言“气相色谱分析”是近代重要的分析手段之一。由于它具有分离效能高，分析速度快，定量结果准确，易于自
