Recommendations for Degassers
CAUTION
Liquid inside the degasser
In case a low boiling point solvent condensates or there is a leak, liquid can accumulate inside the degasser chambers, and this will compromise performance.
When this happens,
- Purge all solvent channels with isopropanol.
- Keep unused channels filled with isopropanol.
Check compatibility of solvents with degasser and application
Use the standalone standard degassers (G1322A or G7122A) for RI applications, flow rates higher than 5 mL/min, with low boiling point solvents (< 60 °C) and with hexane, tetrahydrofuran and any halogenated solvents.
Use integrated or a standalone high-performance degasser (G4225A) for all other applications.
If enough vacuum for the optimal degassing performance cannot be reached or maintained (as indicated by yellow or red status LED in standalone degassers, or specific error messages on integrated degassers), power cycle the module.
If after power cycling vacuum still cannot be reached or maintained on integrated degassers, use the Evacuation Mode, available in the instrument control screen of Agilent Lab Advisor.
NOTE
Follow the instructions prompted on the screen when starting the Evacuation Mode.
