随着我国社会主义建设的迅速发展,对有机分析的要求越来越多,也越迫切。特别是对不易挥发和热不稳定性的有机产品的分析,已长期未能妥善解决。近年来,应用气相色谱的理论,已使古老的液体色谱获得了新生,飞跃进入了一个新时代。对这类产品的分析,在应用上取得了很大成绩。目前很多国家的液体色谱仪器的产量不断增加,检测系统也在不断发展。除当前常用的全波长或紫外(UV)或示差折光(DR)检测器外,还有几种有前途的检测器,如:喷射冲击检测器(SID)、盘式氢火焰离子检测器(FID-DC)、介电常数检测器(DCD)和液体色谱用电子捕获检测器(ECD)等,均正在研制中。现在着重介绍介电常数检测器。这是一种利用物质的介电常数的方法,曾在气相色谱上
With the rapid development of China’s socialist construction, the requirements for organic analysis are more and more urgent. In particular, analysis of organic products that are not easily volatile and thermally unstable has long been unsuccessful. In recent years, the application of gas chromatography theory, ancient liquid chromatography has gained a new life, leap into a new era. Analysis of such products, made great achievements in the application. At present, the production of liquid chromatography instruments in many countries is constantly increasing, and the detection system is constantly evolving. In addition to the commonly used full wavelength or UV (UV) or refractive index (DR) detectors, there are several promising detectors such as SID, FID -DC), dielectric constant detector (DCD) and liquid chromatography with electron capture detector (ECD), are under development. Now focus on the dielectric constant detector. This is a method of using the dielectric constant of a substance that used to be on a gas chromatograph
