I'm working in an environmental lab that analyzes waste streams for VOCs on an Agilent GCMS (7890A and 5975C, respectively). I've been doing some maintenance that doesn't appear to have been done as often or as recently as it should have, as well as had the AC board replaced last week due to repeatedly blown primary fuses.
While the GCMS was down prior to the service call, I figured it was as good an opportunity as any to change the column for what was labelled as an unused, appropriately stored column. Once everything was running again, however, it became abundantly clear that this column is not only used, but based on the severely noisy baseline and the column bleed, it was not taken care of very well.
So I am accutely aware that the only true solution is a new/maintained column, which I will be installing as soon as my ferrules arrive.
Now, my question to you all, is there any possible way I could squeeze whatever life is left out of this column while waiting for the ferrules? I baked it out once and am baking it out again, but it does almost nothing to subdue the rising baseline. Would solvent rinsing help ease the bleed or is this column DOA?
Thanks for your time, this was my first topic on this forum, but I've been reading along for a while now.
