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 and FLD.

4. Dual-wavelength detection, two wavelengths canbe detected at the same time.
