我国1985年版的国biao方法测定溶剂残留,其标准溶液配制是采用无杂质峰的机榨油作溶剂,自1996年以后,国标法采用具有"万neng溶剂"美yu的N,N-二甲基乙酰胺.,发现用这两种不同溶剂配制的标准溶液在气相色谱上相同条件下测定结果竟有很大差别.测定过程如下。
此柱为浩瀚色谱技科研所技术人员通过上万次的测试，研发出的色谱柱，柱效高，分析时间短，寿命长，质保3年，部分客户使用5年以上没有换过。

China's 1985 version of the Guobiao method for the determination of solvent residues, its standard solution is prepared by using machine oil without impurity peaks as solvent. Since 1996, the Guobiao method has used N, N-dimethylacetamide with "Wanneng solvent" Meiyu, It is found that the determination results of the standard solution prepared with these two different solvents are quite different under the same conditions of gas chromatography. The determination process is as follows.
This column is a chromatographic column developed by technicians of the Oceanwide Institute of Chromatographic Technology through tens of thousands of tests. It has high column efficiency, short analysis time, long service life, and a warranty of 3 years. Some customers have not changed it for more than 5 years.
