As you know, Trihalomethanes are a bunch of molecules, not a particular one. So, you need to be aware of what are you exactly interested in.
However, there are few instruments e.g. HPLC-MS, GC-MS which may help you in detection and determination of the amount/recovery of an exact molecule- but not all of them at once.
