Analytical HPLC-A7840

Description :

Analytical HPLC-A7840 system with 0.001 to 9.999 ml / min flow rate range, offers three method measurement: dual wavelength detection, wavelength time program and stop pump scanning. Integrated with a single and dual wavelength UV-Vis detector with a range of 190 to 700 nm to analyse sample’s absorption at different wavelengths and high-pressure pump achieves accurate solvent delivery with high-precision and low-fluctuation.
