This HPLC system is equipped with high-pressure constant-current pump and UV detector. Pressure pulsation is controlled by diaphragmatic damper in seconds. The UV detectors helps in identification of samples and elutes that are colourless, odourless in nature. There is auto boot detection function available in this HPLC system.
