On-Line Mobile Phase Degasser for HPLC

The Degassex Model DG-4400 on-line degassing system is designed to rapidly and efficiently remove dissolved air from all HPLC mobile phases. The system replaces the tedious methods of helium sparging or ultrasonication. Important for ensuring optimum pump and detector performance, the small, modular unit can be used with any HPLC pump or system. Dissolved oxygen is removed in-line up to 0.6ppm to provide a powerful and efficient degasser. Based on the principle of continuous vacuum filtration across a gas-permeable membrane, the DG-4400 contains four solvent channels, is CPU-controlled and offers built-in self-diagnostics. The entire flow path is biocompatible, with all wetted parts composed of Teflon/PEEK. A universal power supply accepts whatever power is available in the lab (from 85 to 260 VAC, 50/60 Hz), so one model fits all.
