Whenever someone tells me that glucose is the preferred fuel because we burn it first, I tell them that we burn alcohol before anything else. Using that logic, we should all be hocked up on liquor 24/7 . What makes real sense though, is that the body will metabolize the most toxic fuels first.
Some tips on electronics in cold: 1  Most electronic components are not damaged by ânormalâ cold temperatures. 2  Condensation can be a problem, if the temperature cycles between warm and cold with humidity.  Batteries lose capacity in cold (battery powered devices might not work in the cold)
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.
