As a mature analytical method, chromatographic technology is widely used in the production and research fields of countries around the world. At present, whether it is gas chromatography or high-performance liquid, chromatographic ion, and chromatographic capillary electrophoresis abroad are the tools of choice for analysis and testing in all walks of life, especially As a chromatographic technique in scientific research, it is an essential analytical method.
Chromatography (chromatography) is a separation technique that came into being with the development of modern chemical technology. At the beginning of the 20th century, the Polish botanical chemist Twist in Russia first put plant extracts into a glass tube filled with calcium carbonate. Because the flow rate of the plant extract in calcium carbonate was different, the distribution Different colors are presented, so that effective separation of various plant extracts can be performed. By 1907, Zwitter's paper was published in Russian. He named this method chromatography, or Chinese chromatogram, which is the origin of the term modern chromatography. However, because Zweit had no visibility at the time, and not many people could read Russian, and soon after the outbreak of the First World War, Zweit's separation method had been kept in a high cabinet.

At present, whether it is gas chromatography or high-performance liquid, chromatographic ion, and chromatographic capillary electrophoresis abroad are the tools of choice for analysis and testing in all walks of life, especially As a chromatographic technique in scientific research, it is an essential analytical method. The chromatographic technology in China has also made considerable progress in recent years, but due to the constraints of financial instruments and equipment, chromatography has not been widely used in China like developed countries (except for gas chromatography technology). There are broad prospects for further development and utilization.
In the early 1980s, ion chromatography has been widely accepted by people. The sales volume of ion chromatography is increasing at a rate of more than 15% every year. The American Chemical Abstracts and the Analytical Chemistry Abstracts in the United Kingdom specifically divide ion chromatography into an independent category. The JournalofChromatographyScience is divided into four types of liquid chromatography, gas chromatography, ion chromatography and capillary electrophoresis when introducing chromatographic instruments every year. The International Conference on Ion Chromatography has been held every year in the world, and 14 sessions have been held so far. In China, a national ion chromatographic conference and some regional ion chromatographic collaborative meetings are currently held every two years. The speed is moving forward.
