Analytical HPLC-A7835 Catalog

Overview

Analytical HPLC-A7835 system is equipped with a flow rate range of 0.0001 to 10 ml per minute. Integrated with a single and dual wavelength UV-Vis detector with a range of 190 to 800 nm that analyzes sample’s absorption at different wavelengths and a high pressure pump providing continuous consistent flow. Built in column heater provides reproducible retention time.

Features :

Compression compensation ensuring gradient repeatability
Low pressure gradient
Detector ( Deuterium or tungsten lamp )
Simultaneous working of deuterium and tungsten lamp
Automatic sample injector ( Autosampler )
External pump control by panel or computer software
Auto save last detected records by the detector
10 point calibration pump for linear pressure control
Error alarm function for over pressure ,under pressure and leakage
