[PointlessDirection]

Looking for some help as to why my gas filter will all of a sudden be depleted within a matter of a day. I am running GC on a Perkin Elmer Clarus 680. I am using Ultra-Pure Helium and a have a Restek Helium-Specific Super Clean Purifier.
The problem usually arises when the building has a power outage, I will come in the next day and my oxygen indicator will be completely depleted. It has happened twice since January(at random intervals), Before that the filter had been in use for  roughly 2 years. Any help would be appreciated!
