Hi,
One of the PI's wants
to measure Y89 on our 500 MHz Varian VNMRS spectrometer. I found an ancient
10 mm low frequency probe that can do 15 to 50 MHz in one our cabinets that
I'd never used. I got the probe to tune to the 24 MHz needed for Y89 via mtune
but can't observe anything for either the 200 mM or 1 M yttrium nitrate
solutions.
Since I've never done
anything this low of a frequency before is there anything besides the quarter
wavelength cable that needs to be changed or adjusted on a Varian VNMRS? I
saw in the probe manual that a switch needed to be flipped on the pre-amp but
I assume that is for an early 1990's console.
The probe is probably
in need of service since it was here decades before I was, but any suggestions
would be greatly appreciated.
thanks,
Stephen
