In super-dry solvents.
I need such a method to detect & determine the amount of trace water in a
boiling reaction mixture.
Please help, Peter.

Karl Fischer measurements would probably be precise enough.

Hope this helps.

GC(/MS), HPLC, Karl-Fischer titration (down to 10 ppm minimum).

Maybe FTIR or NIR?

You might try No-D NMR, recently published by a professor from
Minnesota State, I believe.
