Initial Purge Run
Before the Generator is connected to the application, the Generator
should be operated in isolation (i.e. not connected to the application)
for thirty minutes. This is to ensure any impurities present are purged
from the system. failure to do this may harm the application.
Connect the Generator to the mains and switch on.
Pressure will start to build in the internal storage tanks which can be monitored by
watching the output pressure gauge on the front panel. This will climb to the factory set
pressure as noted in the specifications.
Once this pressure is reached, the compressor will continue to run until the internal tank
upper pressure limit is reached and the compressor has run for a period of at least two
and a half minutes.
The compressor will then rest until the internal tank lower pressure limits is reached.
Once this limit is reached the compressor will switch back on again. This compressor
cycling is normal and will continue throughout the operation of the Generator.
When the system has been operated for a period of 30 minutes, all the internal pipe-
work and storage tanks will have been purged with Nitrogen.
The Generator is now purged and the tubes can be connected at the rear of the unit.
Connecting to the Application
Once the initial purge run of 30 minutes has completed the Generator is now ready to
be connected to the application.
The pressure in the internal storage tanks must be allowed to dissipate
before connecting the Generator to the Mass Spectrometer
Depending on the size of the applications inlet, attach either the 6mm Push-Fit or ¼”
Compression fitting to the outlet of the Generator. Using the appropriate sized Teflon
tubing supplied, connect the outlet of the Generator to the inlet on the application.
If you require more tubing than is supplied please refer to the Tubing Lengths section.
Once the tubing is connected to the application, please ensure that it is
thoroughly checked for leaks. Even the slightest leak in the gas supply
between the Generator and the application can lead to a reduction in
efficiency.
