In recent years, the demand for the application of high-performance liquid chromatography technology in the field of analysis and testing has been increasing. Saizhi Technology has closely followed the market demand and launched domestic high-end new products through independent research and development and production: LC8000 binary high-pressure automatic system (UV/AD) and LC8000 quaternary low-pressure automatic system. This not only meets the diverse needs of users, but also enriches the company's product line. This is a small step for Saizhi Technology, but a big step for the domestic high-end analytical instrument market.
