Agilent G1379B Vacuum Degasser 1200
The Agilent 1200 Series micro vacuum degasser, model G1379B, comprises a 4-channel vacuum container, including 4 micro structured membranes, and a vacuum pump. When the micro vacuum degasser is switched on, the control circuit turns on the vacuum pump, which is operated with constant speed and voltage generates a partial vacuum in the vacuum container. The pressure is measured by a pressure sensor. The micro vacuum degasser maintains the partial vacuum with the help of a controlled leak in the degasser’s proportional valve and by varying size of the controlled leak within the proportional valve, depending on the signal from the pressure sensor.
The LC pump draws the solvents from their bottles through the special plastic membranes of the vacuum container. As the solvents pass through the vacuum chambers any dissolved gas in the solvents permeates through the membranes into the vacuum container. The solvents will be almost completely degassed when leaving the outlets of the micro vacuum degasser.
