DG3100 & DG3110 Online Degasser

The DG3100 and DG3110 online degassers employ an automatic continuous vacuum degassing method to efficiently remove dissolved gases from mobile phases, ensuring stable liquid chromatography performance. They feature high degassing efficiency, continuous operation, and low noise. Two models are available: DG3100 (2-channel) and DG3110 (4-channel), providing flexibility for different system configurations. All fluid-contact parts are made of PEEK and Teflon AF, offering excellent chemical compatibility across a wide pH range (0–14) and resistance to common acids, alkalis, organic solvents, and surfactants. Status indicators (power, vacuum, and fault) allow real-time monitoring of operation and quick diagnosis of leaks or vacuum signal errors.

Performance

The DG3100/DG3110 degasser continuously removes dissolved gases from liquid chromatography mobile phases, effectively eliminating bubble formation during solvent mixing. This prevents pressure fluctuations, flow-rate inaccuracies, column efficiency loss, detector baseline drift, and sensitivity degradation, thereby ensuring stable, reproducible, and high-performance LC analysis. It is equally suitable for any other application requiring reliable online degassing.
