This is an instrument that is used in the detection and analysis of liquid compositions. It is characterized by the international advanced level of processing technology, the overall structure with high strength. With the advanced idea of pressure and leakage alarm deign, all modules adopt the design of intelligent monitoring alarm. It is suitable for medicine food, chemical environment, scientific research and other fields. Combined with new technology and intelligent software, HPLC system has a strong flexibility and applicability. Detection wavelength range is wide (190-800 nm), detection sensitivity is higher.
