Issue with GCD

After sitting in standby mode for awhile (days), when my GCD first turns on the filaments (after a 3 min solvent delay) there is immediately a broad peak that lasts perhaps 10-15 seconds, and it presents very different masses depending if you sample it at the beginning, middle or end. It is weaker on the subsequent samples, but never seems to go away altogether. I assume this is from junk accumulating on the filaments that then burns off. But why does it always seem to be there?
