The fountain cell: a new tool for chemiluminescence analysis by flow injection

Abstract

A chemiluminescence (CL) system that combines the simplicity and reproducibility of sequential injection analysis (SIA) with the radial flow properties of the fountain cell was developed. Optimum conditions for SIA involving three overlapping zones were deduced and the analytical utility of the system was demonstrated by the determination of hydrogen peroxide and glucose, both analyses based on the luminol reaction. The results obtained show that the combination of SIA and the fountain cell can be used for quantitative analysis and a study of reaction kinetics. The system has minimum reagent consumption and can be evaluated without any reconfiguration of the equipment or reagents involved in a given analysis.
