一、修订背景凝胶色谱仪是一种尺寸排阻法液相色谱,其通常由溶剂贮槽、溶剂泵系统、进样器、色谱柱、检测器(示差检测器必备)、废液回收装置、数据处理系统等组成。凝胶色谱仪的测量范围由其使用的色谱柱、温度控制范围、检测器类型等因素决定。近年来,在化工、医疗、生物制品等行业中,该仪器已经越来越广泛地应用于环境富集产物、生物医疗产品、新聚合物材料产品的分子量及分子量分布的在线监测与测量。但是,这些国内大量使用的凝胶色谱仪,由于其量值无法溯源,测量准 First, the revised background Gel chromatography is a size exclusion method liquid chromatography, which usually consists of solvent storage tank, solvent pump system, injector, column, detector (differential detector must), waste recycling Device, data processing system and other components. The range of gel chromatography is determined by the column it uses, the temperature control range, and the type of detector. In recent years, in the chemical, medical, biological products and other industries, the instrument has been more and more widely used in environmental monitoring products and biomedical products, new polymer materials, molecular weight and molecular weight distribution of online monitoring and measurement. However, these large-scale use of gel chromatography, because of its value can not be traced, the measurement of potential
