Solvents mixed under these conditions can form micro bubbles from out-gassing caused by the mixing of liquids with dissimilar gas solubilities. These micro bubbles can affect the system in many ways - from impaired check valve performance to a noisy baseline to bubbles being trapped in the detector flow cell.

The DGU-20A utilises an additional channel for degassing the rinse phase of the autosampler. Degassing of the rinse phase is necessary to get the ultimate in accuracy and precision from the injector.

Regulated laboratories will appreciate the DGU-20As ability to output the vacuum level - allowing one to monitor and record its stability throughout the run. All of these features in a compact module designed to stack effi ciently with the Prominence series makes the DGU-20A an indispensable accessory for any HPLC system.

This model is powered by the Prominence 20 series pumps, and can be controlled by Shimadzu software.
