    This Information Applies To: Agilent G1311B/C, G7110B, G7111A/B, G7112B, and G7120A Pumps and Agilent G7122A, G4225A, G1379A/B, and G1322A Degassers Issue The error message "Vacuum Limit Not Reached" will appear if the degasser does not reach a preset limit (default value is 100 mbar) in a predefined time window (default 8 minutes after powering on the module). This may happen for many reasons. One reason may be due to the condensation of vapors from volatile organic solvents. The vapors...

  • What Components determine Gradient Composition and Flow Accuracy in Binary and Quaternary Pumps

    This Information Applies To: Agilent Binary and Quaternary LC Pumps Issue When performing a gradient analysis, it’s important to know what component determines composition if it becomes necessary to troubleshoot chromatographic inconsistencies. Those inconsistencies can manifest themselves as peak retention time shifts (late or early peaks) and merged or missing peaks. Troubleshooting strategy depends on the pump type being used. This article will describe how binary and quaternary pumps create...

  • Unstable Pressure on 1100, 1200, and 1260 Quaternary Pumps

    This Information Applies to: Agilent 1100, 1200, and 1260 LC quaternary pumps. Issue Pressure has been fluctuating or causing ripple. It may cause a noisy baseline and retention shifts, therefore, the quality of chromatograms has worsened. Pressure fluctuations can occur when the pump is not delivering a flow correctly and it affects the separation during analysis. Resolution Air trapped in the pump head Purge the pump, and flush the system with mobile phase or IPA, first without...

Turning Off the Built-in Degasser Within a Pump Module

Answer

This Information Applies To: Agilent LC Pumps with built-in Degasser

Issue

If the built-in degasser is not working and gives an error on power-on, the pump will be in error mode, and therefore no injections can be made. The user may wish to disable [or enable] the degasser, especially in an isocratic run, to be able to still use the pump while the degasser is repaired.

This article details how to disable the degasser.

Steps to follow

  1. Launch Lab Advisor and connect to the Instrument. 
  2. Go to Instrument Control > [Pump model] > Controls > Control > Degasser Controls and select Degasser > Off. (See Figure 1)

Note:  If you turn off the degasser, and cycle power the pump, it will revert to being back on so will need to repeat the preceding steps each time.
