From NMR Wiki. Cryoprobe or Cold probe is a technology where the probe coil and/or built-in signal preamplifier are cooled with a stream of He gas at ~20K.This increases the sensitivity of the probe coil and reduces the level of thermal noise generated by electronic circuits and components of the signal receiver itself.herefore only very high grade helium should be used. Most grade 6 helium is batch tested-the helium is tested and then put into cylinders. The problem is that at that level of purity, the main contaminants come from the inner walls of the cylinder itself.
