There aren't many places drier than Utah, and we don't experience this
problem, at least not often enough to make it a real nuisance. We do put
our keyboards on a static elimination pad and teach the operators to ground
themselves before changing samples, but I get the impression that this
happens in your case spontaneously when no one is touching the
spectrometer.
