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
  • 1.Fast and convenient, can complete the analysis of a sample in a few minutes
  • 2.High sensitivity, the concentration range of ion chromatography analysis is ug/L to mg/L
  • 3.Simultaneous analysis of multiple ionic compounds
  • 4.The separation column has good stability and high capacity

Application Areas

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
