GPCmax™ Integrated Pump, Autosampler and Degasser

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 can be controlled from the front panel or the OmniSEC software. For serious chromatographers, demanding high throughput and the highest reproducibility and accuracy, the GPCmax is the perfect choice.

Degasser & Eluent Sensor

The GPCmax is equipped with an inline degasser to remove dissolved gases and allow optimum performance of the pump. Furthermore, it improves baselines on all the detectors. To avoid damage to valuable GPC columns, the GPCmax includes an automatic eluent sensor which will stop the flow if it detects the solvent supply is dangerously low.

Pump

The dual piston pump of the GPCmax is optimized for GPC/SEC and advanced detector requirements. It provides an extremely low pulsation and stable eluent flow, to allow optimum performance of concentration, viscosity and light scattering detectors. The pump features a unique user programmable soft start/stop to maximize the lifetime of your columns by protecting them from pressure shocks. The pump is compatible with any solvent, even acidic buffers.

Autosampler

The GPCmax features a programmable, variable volume autosampler which handles up to 120 vials and has both heated and cooled sample tray options. The Autosampler provides the system with reliable, accurate and reproducible injection volumes, enabling comprehensive macromolecular characterizations to be made with confidence. In addition, the advanced programming features via the OmniSEC software allows tasks like dn/dc or 2nd virial coefficient (A2) determinations to be completed simply and unattended.
