Water can be detected in GC if you are using Thermal Conductivity Detector. If you are using FID, then water can't be detected because for detection burning is necessary in FID.
In HPLC, detection depends on the presence of the chromophoric group in the molecule. As most of the solvents lack chromophoric groups, they are not detected in HPLC.

As per X-ray Fluorescence theory, when material particle is irradiated with X-ray the electron of innermost orbital of that element atom is exited and emits outside of the atom as photoelecrons, living behind a hole in innermost orbital . This hole is filled by outer orbital electrons. The question is that finely what happens to that photo electon which is emitted outside of the atom?
