自动化中压液相色谱法适用于原油和岩石抽提物的地球化学分析。重量为1至500毫克的样品可以按20个样品一组,成组地自动化连续分析。每一个100毫克的样品其分析时间为20分钟。样品重量在10毫克以上时,相对误差不超过5％。通过进样圈和由马达驱动的二只20通旋转阀自动进样。硅胶型柱子,工作压力为4—11巴,程序调节流 Automatic medium pressure liquid chromatography for geochemical analysis of crude oil and rock extract. Samples weighing 1 to 500 milligrams can be analyzed in groups of 20 samples for automated, continuous analysis. Each 100 mg sample was analyzed for 20 minutes. Sample weight of 10 mg or more, the relative error of not more than 5%. Two 20-way rotary valves are automatically injected through the injection ring and driven by the motor. Silica gel column, working pressure 4-11 bar, program flow regulation
