Application and Progress of Ion Chromatography in Food Analysis

Ion chromatography (IC) is based on the differential promotion of the substance to be tested on the ion chromatography column, so as to separate different substances, and then determine the content of the substance to be tested through the detection instrument. Because of its convenience, high sensitivity and good selectivity, it is widely used in the fields of food detection, industrial production and environmental monitoring. In recent years, with the continuous development of science and technology, the update of ion chromatography and the development with new and efficient coupling technologies have become the focus of research. In recent years, with the upgrading and improvement of ion chromatography, its detection technology for conventional inorganic ions is advancing with each passing day. At the same time, the combined technology of ion chromatography has greatly broadened the application scope of ion chromatography in the field of food. This paper reviews the research results and new trend of ion chromatography in the field of food in recent five years and also provides direction and reference for follow-up researchers.
