I tried the total shutdown once, and decided to not do that again. My
recollection is that some instruments [or their electronics] didn1t like
it, and gave me fits on startup afterwards. Just keeping them above usual
room temp seemed to help a lot, e.g. the lowest temp at which a GC would
3coast,2 maybe 50C. A minimal flow of carrier gas might be best, but I
think just leaving some small heater on kept things 3baked out2 enough to
help a great deal. I would expect some startup problems, but hope that
baking out for a few days with carrier gas flowing should settle baselines
down. pH meter electrodes don1t like it, but can be stored with
protective caps, or if dried out can be brought back by rehydrating,
soaking in acid, then base, etc. I am not an electronics geek, but
preventing moisture from condensing on circuit boards I think would be a
good idea.
Good luck.
