What's a good high precision analysis technique (after GC) to measure trace isopropanol in water samples?

Looking to measure trace IPA content in water samples.


Only GC I have access to doesn't take samples with water. Different columns not an option.




Other than finding *any* way to get access to a compatible GC (and yes, you can change columns), one might:


Extract the IPA into an organic solvent and *then* try an IPA shoot. "Salting" the aqueous solution might help, but adding steps for trace analysis adds error, particularly since IPA is volatile.


One might consider speaking to their supervisor about the issue.
