摘要
运用５Ａ分子筛分离柱，使用正交试验优选实验操作条件，用分压配气法得到不同含量的标准气，将测定的数据用最小二乘法曲线拟合得到”回归直线方程为标准工作曲线，定量分析异丁烷中微量正丁烷含量。
sing the separation column of 5 A molecular sieve and under the preferred experimentoperation conditions of orthogonal test, thestandard gases with various contents were obtained by the differential pressure gas preparation method. The determined data were fitted with the curves of least square method to achieve the regression linear equation as the standard working curves and the trace amount contents of n-butane in iso--butane were quantitatively analysed.
