Photoinduced oxidation of a tris(2,2'-bipyridyl)ruthenium(II)-peroxodisulfate chemiluminescence system for the analysis of mebeverine HCl pharmaceutical formulations and biological fluids using a two-chip device.

A new method for the analysis of mebeverine hydrochloride (MEB) has been developed using a two-chip device. The method is highly selective, sensitive, rapid and consumes minute amount of reagents. The developed method is free of interference from the degradation products of MEB and from common ingredients present in pharmaceutical formulations.

Analysis of fexofenadine in pharmaceutical formulations using tris(1,10-phenanthroline)-ruthenium(II) peroxydisulphate chemiluminescence system in a multichip device.

A simple, rapid and sensitive method has been developed for the analysis of fexofenadine (FEX) in pharmaceutical formulations, using a tris(1,10-phenanthroline)-ruthenium(II) [Ru(phen)(3)(2+)] peroxydisulphate chemiluminescence (CL) system in a multichip device. Various parameters that influence the CL signal intensity were optimized. These included pH, flow rates and concentration of reagents used.
