Abstract
Capillary electrophoresis with simultaneous ultraviolet absorbance and laser-induced fluorescence detection is applied to identify and quantify selected amines in beer following derivatization with 7-chloro-4-nitrobenzo-2-oxa-1,3-diazole. Quantitation was performed using the method of standard addition in order to avoid pH-dependent variations in the reactivity of the derivatizing agent with the added benefit of verifying peak identity. An inexpensive and "easy-to-use" on-column fiber optic fluorescence detection cell is described and implemented in the analysis.
