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.
