20A5 is an on-line degasser that uses fluoroethylene membrane. The internal capacity is The degassing efficiency has also been improved, ensuring thorough degassing even at high .. In addition to the column, various other parts and units can be accommodated, including a manual injector, gradient
5.5. Kit for small sample volumes. 5.6. Kit for manual injections. 5.7. Calibration with automatic dilution . 1484 (instructions for the determination of total organic carbon and dissolved organic carbon), the difference .. users' workload, as the instrument automatically carries out the dilution, acidification and degassing steps.
Dear colleagues. I have a problem with degasser. After switching on equipment red light permanently appears. Turning off and on the pump (according to manual) doesn't help. I will be grateful for any advices. Regards Sylwia. Re: Shimadzu DGU-20A5 degasser problem. avatar: tkubowicz. Posts: 305
Removing dissolved gases in mobile phases is an important step for ensuring proper function of pump check valves, and to prevent outgassing in the detector flow cell. The degassing units feature extremely efficient degassing in a low-volume, compact design. Each degassing unit can be powered by a LC-20A or LC-30A

Solvent Delivery Problems Due to Bubbles Generated Inside the Mobile Phase Bottle. If bubbles form in the mobile phase bottle, it indicates the mobile phase has become supersaturated with dissolved air. For example, this could be caused by the following: (1)Increase in Liquid Temperature This can occur when using cold
This type of Degassing Unit is installed between the mobile phase bottle and solvent delivery pump and is so widely used that it is commonly called a Degassing Unit. These Degassing Units maintain a vacuum pressure on the outside of a resin membrane tube and utilize the permeability of the membrane to remove smaller
