Double System Ion Chromatography Instrument with Conductivity Amperometric Detectors
Introduction of Dual System Ion Chromatography Instrument
Ion chromatography (or ion-exchange chromatography) is a chromatography process that separates ions and polar molecules based on their affinity to the ion exchanger. It works on almost any kind of charged molecule—including large proteins, small nucleotides, and amino acids. The two types of ion chromatography are anion-exchange and cation-exchange. It is often used in protein purification, water analysis, and quality control.
Features of Dual System Ion Chromatography Instrument
1. Ideal model for high efficiency, high sensitivity, high reliability ion chromatography; dual system one machine realizes yin and cation simultaneously;
2. Conductance and electrochemical detectors meet the detection requirements of different substances;
3. Can realize two-dimensional ion chromatography (valve switching) and post-column chemical derivatives
4. Dual system simultaneously detection design allows customers to maximize efficiency, further shorten detection time
5. Double pump, column temperature box, modular design of the crash generator, the user can choose the required system configuration;
6. It can be equipped with high-end double pump double system detection, and can also customize single pump single system detection according to customer needs, and personalize your chromatography solution.
