Quaternary Pump High Performance Liquid Chromatography System With UV Detector
Quaternary Pump HPLC Cromatografía with UV Detector High Performance Liquid Chromatography Instrument
Introduction of Liquid Chromatography Instrument
High Performance Liquid Chromatography (HPLC) is a form of column chromatography that pumps a sample mixture or analyte in a solvent (known as the mobile phase) at high pressure through a column with chromatographic packing material (stationary phase). HPLC has the ability to separate, and identify compounds that are present in any sample that can be dissolved in a liquid in trace concentrations as low as parts per trillion.

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. Wavelength scaning: the absorption spectrum can be scanned in the entire range of the light source.
3. A variety of detectors available, such as DAD, ELSD,UVD,RID and FLD.
4. Dual-wavelength detection, two wavelengths canbe detected at the same time.
