If you have access to an HPLC, easiest analytical solution would be
separation on any standard reversed phase ODS column with a MeoH/50 mM
ammonium phosphate buffer pH 2.6 eluent (ca. 40:60) and UV dectection
at 254 (or 210, if you need more sensitivity) nm wavelength.

Very sensitive, fast (5 min), automatizable, and little interference 
(since separation) of related compounds.

Hope this helps.
