The Chromatography System is a modern separation device that combines with suitable adsorbents to efficiently and cost-effectively separate many substances that are difficult to separate using conventional methods. Since its introduction in the 1960s, it has quickly found applications in industries such as chemical engineering, food, and pharmaceuticals. This continuous separation and purification technology produces an effect similar to reverse separation of adsorbents and materials by changing the positions of material inlet and outlet. As a result, it has strong separation capabilities and saves solvents, making it widely used in the fields of biotechnology, pharmaceuticals, food, petroleum, and fine chemicals in both production and research. It is particularly suitable for chiral compounds, sugars, monoclonal antibodies, and more.
