摘要
我国甲醇生产企业多,甲醇中乙醇含量高低直接影响着甲醇的产品质量,通过对内标法和外标法的比较达到更精确的测定数据及选择合适的测定方法。
There are many methanol production factories in China. The content of ethanol in methanol directly affects the quality of methanol product. By comparing the internal standard method with the external standard method,more accurate determination data and appropriate determination methods can be obtained.
