摘要
本文采用气相色谱法测定酒中的甲醇,色谱柱为HP—INNOWax毛细管柱(30m×0.32mm×0.25μm),进样分流比20:1。得到线性回归方程为Y=250.11X-13.03,相关系数r=0.9978。方法操作简便、快速,能满足检测饮用酒中甲醇含量的要求。
A high performance gas chromatography method with FID for measuring methanol in alcohol is presented in the paper. Chromatography was performed on a HP-innowax capillary column. The calibration curve was linear within the range of 0.05-0.40mg/L. Regression equation: Y=250.11X-13.03, r=0.9978. The recovery we have detected is 98.4%. Conclusion: this method is simple, accurate and convenient.
