Ion chromatograph ICIt is a type of liquid chromatography method used to analyze anions and cations. This method has the advantages of good selectivity, sensitivity, rapidity, and simplicity, and can simultaneously determine multiple components.
Normally, ion chromatography can be divided into three types: ion exchange chromatography, ion exclusion chromatography, and ion pair chromatography. Ion chromatography is a type of liquid chromatography, also known as ion chromatography or modern ion chromatography. It differs from traditional ion exchange chromatography column chromatography mainly in that the resin has a high degree of cross-linking and a low exchange capacity, the injection volume is small, and the eluent is usually transported by a plunger pump for online automatic continuous conductivity detection of the eluent.Ion chromatograph ICThe principle of separation is based on the reversible exchange between dissociated ions on ion exchange resins and solute ions with the same charge in the mobile phase, as well as the difference in affinity of the analyte solute to the exchange agent. Suitable for separating hydrophilic anions and cations.Ion chromatograph ICThe basic components are a flow compatibilizer, a high-pressure infusion pump, an injector, a chromatographic column, a detector, and a data processing system. In addition, mobile phase online degassing devices, automatic injection systems, mobile phase suppression systems, post column reaction systems, and fully automatic control systems can be configured as needed.
choiceIon chromatograph ICThe basic principle is:
1. Product cost-effectiveness;
2. Strength of product manufacturers;
3. The operating cost and parts guarantee of the product;
4. After sales services provided by the manufacturer.
