Agilent/HP G1322A/G1379A

Degasser Upgrade Service

chromatography in every way

Turn your old 1100 Degasser into an efficient, long-life unit with quicker vac down times.This is a service which will upgrade your old G1322A/G1379A 110 Degasser into a fully refurbished G1322s low-volume, quick start-up unit with the following added benefits:

• Long life - 5 years continuous run times

• Quicker vac down times

• Internal channel volume: 480µL

• DuPont / Teflon® AF membrane

• Closed loop vacuum control means constant vacuum (variable RPM)

• Advanced error & leak checking functions

• Short vacuum pull-down times, typically 3 mins

• Extremely quiet operational noise

• Remove pre-bubbles formed by cavitation vs bubbles formed by off-the-floor eluent reservoirs

• Four channels

• Wetted parts - PEEK & Teflon® AF

• THF resistant chambers version available

• Pump head purge eliminates need for purge valve

• Eliminate baseline fluctuations due to the vacuum pump

• Fully compatible with Agilent event I/O for shutdown & Chemstation interaction

Note: Your current G1322/G1379 does not need to be in working order.

This exchange program operates on the basis whereby we deliver an off-the-shelf updated Jaytee 1100 G1322S/G1379S degasser with specification as described.

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

Vacuum Pump Technology & Smart Control

Installed in the G1322S 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.
