My TCD (agilent) is giving me negative peaks - right around where my peaks of interest are to elute.
I think this may be damage to my filament from acids on my analysis - can it be anything else?
I've tried baking out the filament w/o luck.

thanks

Yes, you could have your polarity reversed.

Likely you can reverse polarity through the keyboard or the computer, or you can swap the TCD leads readily on models such as 5890.
