The Q-Grad System provides reproducible high-pressure quaternary gradient capability for HPLC applications
The Q-Grad System provides reproducible high-pressure quaternary gradient capability for HPLC applications. The four high-performance pump heads can be programmed through an independent keypad unit or from optional PC-driven software. The system includes an easy-to-use high-sensitivity Model 500 variable UV wavelength detector designed for routine applications. It uses an intelligent keypad controller for programming and storing gradient methods. It can also be used to prime individual pump heads and to apply flow rate corrections if necessary. A very efficient internal pulse damper mixer ensures high performance gradients.
The company also offers columns and data handling systems.
