What is Ion Chromatography?
Ion chromatography is a kind of high-performance liquid chromatography, so it is also called high-performance ion chromatography (HPIC) or modern ion chromatography. It is a liquid chromatography method for analyzing anions and cations. At present, HPIC analysis technology has been applied to various fields such as environmental monitoring, health and epidemic prevention, medicine, chemical metallurgy, geology, hydrology, agriculture, feed, electronics industry, electric power, atomic energy, food and beverage, drinking water and so on. , Scientific research, education, etc.

Features of Ion Chromatography
- Fast and convenient, can complete the analysis of a sample in a few minutes.
- With high sensitivity, the concentration range of ion chromatography analysis is ug/L to mg/L.
- Simultaneous analysis of multiple ionic compounds.
- The separation column has good stability and high capacity.

Application Areas of Ion Chromatography
IC is mainly used for the analysis of environmental samples, including anions and cations in samples such as surface water, drinking water, rainwater, domestic sewage and industrial wastewater, acid deposits, and atmospheric particles. In addition, it has a wide range of applications in the fields of food, sanitation, petrochemicals, water, and geology.
Environment: atmospheric composition (dust, particulate matter, fog, acid gas), acid rain, water quality analysis
Food: Contaminated ingredients, additives, inherent ingredients, adulteration, production process monitoring
Agriculture: Pesticide, fertilizer, soil, feed, food, plant analysis
Medicine: blood, urine, infusion composition, clinical examination, human trace element analysis
Biology: Protein separation and purification
Pharmaceuticals: analysis of plant medicinal materials, mineral medicinal ingredients, and preparation ingredients
Materials: metal materials, semiconductor materials, surface treatment, ultrapure water analysis
Industry: Raw material analysis, product quality control, electrolytic plating solution analysis, papermaking
Daily chemicals: analysis of cosmetics, detergents, cleaning agents, raw materials, and product components
