Spinlanders,

another point on cryoprobes that seems not to be in the list kindly posted by Josh.
We have a student trying to get reasonable T1 measurements for water in
DMSO in a Bruker cryoprobe (500MHz).

Apparently, it is very hard to get around the radiation dumping
effects, even trying capillaries, gradients along the recovery time. He
always find about one sec relaxation time, way too short ?
Could you please provide some advice ? I'll post a summary.

Thanks,
Stefano Caldarelli
