Hi all,
In our facility we currently run our spectrometers on compressed/dried
air for routine work and switch to N2(g) for high VT work. If my
understanding is correct, N2(g) is preferred over compressed air because
it's generally drier and/or easier to dry, and it won't damage the probe
electronics at high temperatures. Our house N2(g) pressure is too low
though to use it exclusively (can't eject/spin samples). What I'm
wondering is:
1) Is it possible to hook up a compressor in the lab to pull in the low
pressure N2(g) and compress it further for delivery to the
spectrometers? I imagine a reservoir would be necessary (as was
mentioned recently in the discussion on air-dryers) to buffer the
pressure changes when the compressor turns on and off.
2) Would another option be to always just use our house N2(g) as the
probe electronics cooling gas and use the compressed air for
VT/eject/spinning? The dryer on the compressed air seems to do a decent
job of supplying dry gas.
Thanks for any input. I will summarize for the archives.
Sincerely,
John T.
