Analytical High-performance Liquid Chromatography NHLC-400 is an advanced, highly effective analytical HPLC system that includes a UV-Vis detector with a wavelength range of 190 to 700 nm, a DAD (Diode Array Detector) detector with a wavelength range of 190 to 800 nm, and a high-pressure constant flow pump and low-pressure quaternary constant flow pump with a flow range of 0.001 to 10.000 mL/min (step 0.001 mL/min). This HPLC system provides accurate, reliable results with improved working efficiency. Powerful software is integrated to regulate, capture, and analyze data, as well as manage the operation
