HPLC Degasser / HPLC Vacuum Degassers

HPLC degassers remove dissolved gasses from the mobile phase solvent used in an HPLC or other LC instruments leading to lower baseline noise and improved analysis. Dissolved gasses such as oxygen or carbon dioxide can negatively impact chromatographic systems by decreasing sensitivity due to increased baseline noise or drift. Laboratories in numerous industries including biotechnology, pharmaceuticals, and environmental monitoring employ HPLC vacuum degassers to improve their chromatography reproducibility. HPLC degassers work by passing the mobile phase solvent through a gas-permeable tube with a constant vacuum pressure maintained to allow the gasses to pass through the membrane while retaining the solvent inside the tube. When comparing HPLC vacuum degassers, be sure to consider the various flow rates offered by different models and ensure this will be compliant with your analysis needs. Also, be sure to compare the capacities of the HPLC degassers as certain models offer the ability to degas multiple solvents simultaneously.
