The GPCmax is the world’s leading solvent and sample delivery module exclusively for GPC/SEC applications. Designed by GPC/SEC practitioners to deliver unparalleled robustness and performance for these demanding applications, it provides the reliable and stable chromatographic foundation for the Viscotek advanced detection systems.
The GPCmax is an integrated GPC/SEC pump, degasser and autosampler. It works in combination with the TDA, SEC-MALS, 270 or RI detectors to form a complete GPC/SEC system.
The pump is an isocratic GPC/SEC pump designed for constant and low pulsation solvent flow and includes programmable ramp rates to protect the columns from sudden changes in pressure. The degasser removes any dissolved gases from the solvents. In combination, the pump and degasser help to reduce detector noise and maximize sensitivity on concentration, light scattering and intrinsic viscosity detectors.
The GPCmax includes a variable injection volume autosampler that holds up to 120 standard 2 mL sample vials. A 60 vial cooled (4-40°) sample tray and a 60 vial heated sample tray (fixed to 65°C) are options. The system can be controlled manually from the on board keypad and display. Alternatively the system can be fully controlled using OmniSEC, Malvern’s complete GPC/SEC software package.
