Hi elsheiki

There are commercially available online gascromatographs. Unfortunately you will experience an extremely variable composition of the carrier fluid, so I am not sure you can suppress the noise.
Moreover, the slug will probably blind the gaschromatograph in a very short time.
Probably the only way is to autosample and monitor offline, maybe with an automatic system, and cross check with lab every now and then.
