Abstract
Titanium dioxide was used as a photocatalyst to improve the yield and rate of product formation in a post-column derivatization reactor for microbore liquid chromatography. The photo-catalytic reactor demonstra ted an increase in sensitivity of greater than one order of magnitude for the electrochemical detection of phenylalanine compared to the mor e typical opentubular photolysis reactor. The detection limit for phen ylalanine was also decreased by two orders using the photo-catalytic r eactor. (C) 1997 Elsevier Science B.V.
