气相色谱法测定空气中环己酮等有机杂质的质量分数

摘要

采用气相色谱法同时测定空气中的环己烷、环己酮、环己醇的质量分数,直接进样,通过毛细柱DB-WAX分析.结果表明,各组分的线性方程分别为y=.1102 x−.23328, y=.007713 x−6105. y=.008912 x+1983.,相关系数均在99.94%以上.实验表明,该方法简便、快速、准确.%　　A method for simultaneous detection of cyclohexane,cyclohexanone and cyclohexanol in workplace by gas chromatography,direct injection,analysis by using DB-WAX capillary column.Results was proved that these samples were separated effectively.The linear equation was y=. 1 102 x−. 23 328 , y=. 0 077 1 3 x−6 105 . , y=. 0 089 1 2 x+1 983 . .Correlation coefficients were above 99.94%,the method had the advantages of easy operation,rapid,accurately.
