Choose solvent reservoirs that provide a snug fit for the reservoir caps
supplied in the startup kit. Waters recommends 1-L reservoirs. Place the
reservoirs in the solvent bottle tray, and set the tray above the solvent
management system components.
The solvent reservoir caps help control solvent evaporation. Three
feather-edged holes in each cap make a gas tight seal around the solvent and
vent tubes.
Install the solvent and vent lines as described in “Connect tubing and
attachments” on page 50.
Degassing solvents
In-line vacuum degassing reduces the total dissolved gas in the mobile phase.
For more information on vacuum degassing, see “Degasser considerations” on
page 30.
Tip: For proper operation of the in-line vacuum degasser, you must fill each
vacuum chamber with solvent. Use the dry prime direct function to prime all
solvent lines.
To control the in-line vacuum degasser from the Status screen:
1. Press Menu/Status.
2. On the status screen, press the Next Page screen key (if necessary) to
display the degasser fields.
3. Select the Degasser mode field, and then press Enter.
4. From the list of degasser modes. select one:
• On – The degasser is always on
• Off – The degasser is always off
5. Select the desired operating mode, and then press Enter.
Results:
• The Vac pump field displays the current status of the vacuum
degasser pump.
