This is a really basic question I've been trying to figure out but so far have had no luck.
Why do people doing GC-EAD (gas chromatography linked to Electroantennogram) always (I've never seen it done another way) pair their EAD with FID to see when compounds elute? It seems to me that you could have a y-splitter that sends 50% of the sample to an MS instead of the FID - which should allow you to detect lower concentrations of compounds of interest (at least I think that would be true) - but I never see this done in the literature. If anyone could clarify this for me it would be much appreciated!
Cheers,
James
