System Components
1260 Infinity High Performance Degasser (G4225A)
The Agilent 1260 Infinity High Performance Degasser , model G4225A,
comprises four separate vacuum chambers with semipermeable tubings, a
vacuum pump and control assembly. When the vacuum degasser is
switched on, the control assembly turns on the vacuum pump, which
generates a low pressure in the vacuum chambers. The pressure is
measured by a pressure sensor. The vacuum degasser maintains the low
pressure by a controlled leak in the air inlet filter and a regulation of the
vacuum pump using the pressure sensor.
The LC pump draws the solvents from their bottles through the
semipermeable tubes of the vacuum chambers. When solvents pass through
the vacuum chambers any dissolved gas in the solvents permeates through
the tubings into the vacuum chambers. The solvents will be degassed when
leaving the outlets of the vacuum degasser.
