Bubble free, trouble free solvent
degassing
Removing dissolved gases from HPLC solvents improves pump performance and reduces baseline and noise levels in UV detection systems
CSI's 6150 range of vacuum degassers provides efficient, effective solvent degassing without the inconvenience, expense and potential hazards of helium degassing Some of the drawbacks of helium degassing are obvious - the logistics of maintaining gas supplies and the cost of helium - less obvious is the risk of toxic solvent vapours being swept in to the laboratory atmosphere by the stream of helium

Two commonly used HPLC solvents, dichloromethane and 2-methoxyethanol, are sufficiently toxic to have been given Maximum Exposure Limits (MELs) by the UK's Health and Safety Executive.
The CSI vacuum degassers use only electrical power, require no gas supplies and no solvent vapours can escape to the laboratory atmosphere.
Units are available with from one to four degassing channels, each capable of removing dissolved gases to better than 1ppm at a solvent flow of 1ml/min - the flow rate range is from 0.2 to 5ml/min.
