Description
The Agilent 1260 Infinity HPLC G4225A high performance degasser is comprised of 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.
