Description: The "Dionex Integrion HPIC System" ion chromatography system from Thermo Fisher Scientific is an instrument for qualitative and quantitative analysis of several ions (fluorides, chlorides, sulfates, nitrates, phosphates, etc.) in liquid samples. The ion chromatography (IC) is commonly used for the analysis of pollutants in the environment, ionic compounds in pharmaceuticals, simple carbohydrates in food and beverages, and the determination of important ions in industry.
The chromatographic column is filled with a specific ion exchanger called stationary phase, which allows the separation of ions. The integrated HPIC system (high pressure IC) with high pressure capacity withstands pressures up to 5000 psi (345 bar) and thus enables faster ion separation while maintaining high resolution chemical analyzes. No additional pre-treatment of the eluents is required for the analysis, as the RFIC system ("reagent free IC") provides automatic preparation of these. Eluent generator operates on the basis of electrolysis using special cartridges, where only ultrapure water needs to be added. Eluted ions are detected by a conductometric Dionex CD detector, which measures the electrical conductivity of the solution.
Analyses are possible by prior arrangement. The cost of the investigation depends on the complexity of the analysis.
