AMMRLers,
We recently joined the cryprobe club after installing our new Avance500
with Prodigy probe. Up top that point, we happily operated using our
main campus compressed air supply with dedicated dryers for our
facility, and also did not use any unprintable power supplies (UPS),
simply accepting that once in a while acquisitions would get halted due
to short power outages/glitches.
Now after operating the Prodigy for a few months, we already had two
instances of the probe warming up due to temporary (30-40min) drops of
the air pressure, so the department is looking into installing an air
compressor dedicated to the NMR lab.
Also, I am not sure what state a sudden power outage would leave a
cryoprobe in, so I am considering a UPS dedicated to the cryocontrol unit.
The questions I have are:
-Does anybody have experience running their own air compressor for their
facility or department, and any considerations/experiences they are
willing to share.
-I am aware that using nitrogen gas from a liquid nitrogen storage tank
is the preferred option for supplying a facility with nitrogen gas, but
that may not be an option for us right now as the main storage tank is
located at the physics building. But I was wondering whether anyone is
operating a smaller scale dedicated liquid nitrogen tank just for their
lab I would like to hear their experience, and whether that is actually
an option. Also, as we are slated for a new building in the next few
years, any argument I can make to push our department to ensure there is
a liquid nitrogen storage tank with high pressure nitrogen gas boiloff
installed with the new building would be helpful.
-What happens if the Prodigy controller suddenly looses power. Is there
some safety built in ? Would it be sufficient to put the Prodigy
control unit on a UPS in order to prevent the probe from warming up
during a short power outage, or would we need to invest into a UPS for
the whole console ?
Thank you very much
