FLD Detector High Pressure Liquid Chromatography Machine in Pesticide Residue Analysis
Description of Liquid Chromatography Instrument
High-performance liquid chromatography or high-pressure liquid chromatography (HPLC) is a chromatographic method that is used to separate a mixture of compounds in analytical chemistry and biochemistry so as to identify, quantify or purify the individual components of the mixture. In very small amounts, the sample mixture to be separated and tested is sent into a stream of mobile phase percolating via a column. The mixture moves through the column at varying velocities and interacts with the sorbent, also known as the stationary phase.

Features of Liquid Chromatography Instrument
1. Two optional modes: binary high pressure and quaternary low pressure
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.
