Diode Array Detector HPLC Chromatography System High Pressure Liquid Chromatography Instruments
Introduction of Liquid Chromatography Instrument
High Performance Liquid Chromatography (HPLC) is an analytical technique used to identify the components in a mixture and separate mixtures of very similar compounds. HPLC can be used to separate the constituents of a compound, tell you how much of each compound is found within the mixture and helps to identify what each compound is. HPLC is the technique of choice when analysing materials for a wide range of organic compounds.

Features of Liquid Chromatography Instrument
1. Two optional modes: binary high pressure and quaternary low pressure. The binary high pressure mode is equipped with a solvent selector valve, which can be extended from binary to quaternary system, greatly improving the flexibility of system configuration.
2. The column oven adopts air bath circulation mode to ensure constant temperature.
3. A variety of detectors available, such as DAD, ELSD and FLD.
4. The standard configuration includes a 120-bit automatic sample injector, which can realize unattended autoinjection process.
