Quaternary High Pressure Liquid Chromatography NHLC-301

Quaternary High Pressure Liquid Chromatography NHLC-301

Quaternary High Pressure Liquid Chromatography NHLC-301 is a quaternary pump chromatography system. It is composed of a low pressure quaternary pump that delivers combination of eluent under the controlled reciprocating valve. It is equipped with tungsten and deuterium lamp as source of light and photo diode array as detector for precise separation and analysis of compounds with high operation reliability for extended time intervals. The instrument features an autosampler and a oven column for accurate loading of samples as well for rapid end results of the analysis.
