AMMRL: low gamma probe?

Hi All,

I have been contacted by a researcher who wants to observe Ruthenium-101 or maybe Ruthenium-99 (the 101 isotope has a higher receptivity), but none of the probes in any of my seven NMRs can tune that low. The Frequency of 101Ru is 5.17% that of 1H, and the frequency of 99Ru is 4.61%. Does anybody have, for example, a 400 with a low-gamma probe that will tune to 18.46 MHz (99Ru) or 20.69 MHz (101Ru)?

Any help is appreciated. I think there are just a couple of samples that could be sent.
