Greetings All,
One of our older Varian (Agilent) 600 Mhz Spectrometers here at Harvard
Medical School, is equipped with a first generation "Chili Probe" with a
stand-alone vacuum pump that does not electronically communicate with the
cryobay or the compressor. This means that if, or when, the vacuum is lost
the compressor will remain operational and a "warm-up" is not initiated,
which would be quite problematic. One logical approach to solving this
problem would be to install some kind of a sensor in the vacuum line that
could send a signal to the computer, equivalent to pushing the "warm-up"
button, in case the vacuum is lost.
If you have encountered a similar situation or simply have a good
suggestion, I'd appreciate your feedback.
Thanks,
Reza
