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.
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
