Quaternary High Pressure Liquid Chromatography NHLC-300

Quaternary High Pressure Liquid Chromatography NHLC-300

Quaternary High Pressure Liquid Chromatography NHLC-300 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.
