Introduction of Ion Chromatography Instrument
Ion Chromatography is a well established ion exchange chromatography technique for the analysis of anions and cations. In contrast to general HLPC systems, often suitable for a wide range of applications, ion chromatographs are chromatography systems specifically adapted for the analysis of anions and cations.
Features of Ion Chromatography Instrument
1. Modular design, flexible conguration, and outstanding functionality
2. Wide selection and outstanding performance chromatography pumps
3. Environmentally friendly, reagent-free ion chromatography
4. High-throughput, multifunctional autosampler design
5. Five-zone temperature control ensures uniform stability at all times
6.Five-zone temperature control mode for separation, detection and derivatization modules provides higher temperature stability.
