Why upgrade your Agilent / HP G1322A or G1379A to a G1322S?

On-line vacuum degassing has been shown to be more effective at removing dissolved gas from mobile phases than other methods. By upgrading to the Jaytee 1322S Degasser you also take advantage of the latest vacuum degassing technologies.

The new Teflon® AF used in the Jaytee1322S is 50X more permeable than older Teflon® PTFE materials, allowing the use of shorter tubing lengths. The volume of each Teflon® AF channel is only 480ul which offers the following advantages:

  • Considerably shorter equilibration / re- equilibration times
  • Very easy and quick to prime
  • Short vacuum pull-down times, typically 3 minutes
  • Removal of pre-pump bubbles formed by cavitation

Degassing Efficiency

Vacuum Pump Technology & Smart Control


Installed in the 1322S degasser is the constant run stepper motor driven vacuum pump which has been specifically designed for maximum degassing efficiency.
Employing micro-stepping closed-loop smart vacuum control permits the upgraded G1322S to maintain a constant vacuum level set-point (50 mmHg).

The pump initially runs at a high speed which provides for a quick pull-down, then, as it approaches the vacuum control point, the RPM is gradually reduced until the desired vacuum level reached. This control strategy allows the G1322S to maintain a virtually constant vacuum that is unaffected by varying degassing loads.
Fluctuations in detector baselines due to vacuum hysteresis are eliminated by not having the pump repeatedly stop and start as is done in the original G1322A/G1379A degasser.

Other benefits of the NEW G1322S technology include:

  • Extremely quiet operational noise
  • Long life Expectancy - 5 years continuous run
  • Pump head purge eliminates need for purge valve
  • Eliminate baseline fluctuations due to the vacuum pump
  • Short vacuum pull-down times, typically 3 minutes
  • Closed loop vacuum control means constant vacuum (variable RPM)
  • Advanced error and leak checking functions
  • Fully compatible with Agilent event I/O for shutdown & Chemstation interaction

General Specifications

Number of channels: 4
Internal Channel Volume: 480 µl
Wetted Parts: Peek and Teflon AF
