美国DIONEX公司生产的离子色谱仪,尤其是新产品DX—500型,它的系统压力可达到35MPa(5000psi),备有两种泵系统(全塑泵和不锈钢泵),还备有电导、脉冲安培和两者相结合的检测器以及紫外-可见检测器,加上各种类型的分离柱子,既可组成典型的离子色谱,也可配置成高效液相色谱使用.因此,在一台仪器上可开展多种成份的分析,如阴、阳离子、有机酸和有机物等.假如配上计算机工作站,更使数据处理趋于规范化.我所自1983年购置离子色谱仪(IC-16和IC-4500)以来,开展了许多项目的检测工作.特别是对于μg·1~(-1)级的阴、阳离子和低分子有机酸的测定,在指导水汽系统的查定,新水处理设备的调试,以及
The ion chromatography manufactured by DIONEX Company of USA, especially the new product DX-500, has system pressure up to 35MPa (5000psi), two pump systems (all plastic pump and stainless steel pump), conductivity and pulse Ampere and a combination of detectors and UV-visible detectors, plus various types of separation columns, can be used in either classical ion chromatography or high performance liquid chromatography. Therefore, on one instrument Can carry out a variety of component analysis, such as the anion, cation, organic acids and organic matter, etc. If equipped with computer workstations, but also to standardize the data processing. I since 1983, the purchase of ion chromatography (IC-16 and IC-4500 ), Many tests have been carried out.Especially for the determination of μg · 1 ~ (-1) levels of anionic, cationic and low molecular weight organic acids, it is of great importance in the investigation of water vapor system, the commissioning of new water treatment equipment, as well as
