My lab has been trying to analyze fluorinated compounds in solvent on GC-uECD for a few weeks now and have noticed that the signal is very low compared to chlorine/bromine. I know that is to be expected, but it is so low sensitivity that it will be hard to analzye at any lower concentration. (Which will be necessary)
I am wondering if anyone out there has done work with fluorinated compounds on GC-ECD and has any advice. (Or knows whether or not this is feasible).
