2.4.1 Vacuum Degas Assembly (Optional)
The vacuum degas assembly provides online eluent degassing at the time
and duration specified by the user. The assembly, which must be installed
in the ICS-1000 at the factory, consists of:

internal capacity of 17 mL
• A dual-stage diaphragm vacuum pump
• A solenoid valve
• An on-board vacuum sensor
• The electronics required to operate the vacuum pump
• Tubing, fittings, and other accessories
By default, the ICS-1000 monitors the degas pressure reading and turns
the degas pump on and off as needed. A different degas operating mode
can be selected from Chromeleon. To select degas operating options from
Chromeleon, open the Server Configuration program, select the ICS-1000
