DGU-3A

Outline of Degasser

The DGU-3A online degasser continuously removes gases dissolved in liquid through a special plastic membrane.

When the degasser is connected to the HPLC pump, the degasser continuously removes gases dissolved in the mobile phase without changing its composition. Consequently, the degasser improves stability and repeatability in HPLC analysis because it prevents genera­tion of bubbles due to dissolved gases, poor delivering of the pump due to bubbles, noise an the baseline of the detector, and fluctuation of the detector baseline due to the variation of dissolved gas concentration.

The DGU-3A has three independent flow paths and the DGU-4A has two independent flow paths. The degassing characteristic per flow path and other functions are common to both the DGU-3A and DGU- 4A, and the only difference between them is the number of flow paths.

The operating principle of the degasser is illustrated below.

The mobile phase passes through the special plastic membrane mounted in the vacuum chamber of the degasser. Gases dissolved in the liquid selectively pass through the membrane into the space in the vessel because of smaller gas molecular sizes, and higher mobility than the liquid, and the close affinity of gases to the membrane. In the above process, gases are removed from the liquid to the space in the vacuum chamber and are then exhausted out of the system.

Specifications:

Degassing characteristics               The concentration of residual dissolved oxygen at the          outlet of the degasser is 1.5ppm max. per flow path when          air-saturated ion-exchanged water at an ambient    temperature of 25°C is passed through the degasser at a           flow rate of 3ml/min max.

Maximum flow rate                           10ml/min (water)

Internal volume                                 About 15ml per flow path

Operating pressure                          2kg/cm ² max. (Use is limited to the suction side, i.e., inlet,   of the pump. Feeding of liquid to the degasser under        pressure is not allowed.)

Connecting tubes                             Teflon tubes of 3mm OD and 2mm ID

Wetted materials                              Special plastic resistant to all solvents (degassing    membrane), Kel-F (connection joints), Teflon (connection         tubes)

Other

• Self-cleaning                                   When the vacuum pump is started or stopped, the   solenoid valve is switched over to draw in ambient air to          prolong the service life of the vacuum pump.

• Safety feature                                 A device is provided to stop the vacuum pump          automatically if the vacuum pump is over-heated.
