UPS and GC-MS? Yes, no?

We have backup generation, and we also recently put all of our instruments on a full-pass UPS system (Weissco Power - www.weisscopower.com) All power to each instrument goes through the UPS system. The nice thing about the system we have is that the power is conditioned and regulated by a UPS circuit that is correctly sized for the demand. If there is a power failure, the UPS keeps everything running on an even keel until the backup generator can come online, and because it is a full-pass system there are no hiccups at all, no voltage or current fluctuations, just smooth, clean power. The downside is cost - around $30,000 for a used system for just our room (4 LC/MS, 2 GC/MS, 5 GC/FID, 1 GC/ECD, 4 HPLC). The units also have very noisy fans, best if they are installed in a soundproof closet, ours are not alas, we have makeshifted a sound absorber that works OK. You should keep in mind also that when we originally designed our lab, we provisioned it with adequate power to begin with, unlike our previous room where we had very dirty "brown" power supplied by a barely adequate service factor. If we had simply installed a UPS system there, we would probably not realize the benefits of the system.
