高效液相色谱检测器是用以连续检测由色谱柱分离流出各组分的一种测量和指示装置。迄今为止,既有专属性的、也有一般的检测器。常用的检测器是按紫外吸收、火焰离子化、折光率、吸附热等原理工作的,但还缺乏泛用的检测器。随着生物学、医学、药学和环境科学的发展,样品的复杂性越来越大,除了柱填料的革新以外,色谱测定中主要关心的问题是检测器的特性。近十年来,由于电化学检测方法的迅速发展,为液相色谱奠定了既灵敏而又具有选择性的检测基础。这些不同类型和各种构造的电化学检测器所具有的优点为选择性好、灵敏度高且具有实际的经济效益。因而,液相色谱-电
High-performance liquid chromatography detector is used to continuously detect the separation of columns by column separation of a measuring and indicating device. To date, there are both proprietary and general detectors. Commonly used detectors are based on UV absorption, flame ionization, refractive index, adsorption heat and other principles of work, but also the lack of general-purpose detector. With the development of biology, medicine, pharmacy and environmental science, the complexity of the sample is getting bigger and bigger. In addition to the innovation of column packing, the main concern in chromatographic determination is the characteristics of the detector. In the recent ten years, due to the rapid development of electrochemical detection methods, liquid chromatography has established a sensitive and selective detection basis. These different types and configurations of electrochemical detectors have the advantages of good selectivity, high sensitivity and practical economic benefits. Thus, liquid chromatography - electricity
