The Individual

This work describes the development of a dedicated, fully automated sequential-injection analysis (SIA) apparatus suitable for simultaneous electrogenerated chemiluminescence (ECL) and amperometric detection. The instrument is composed of a peristaltic pump, a multiposition selection valve, a home-made potentiostat, a thin-layer electrochemical/optical flow-through cell, and a light detector. Control of the experimental sequence and simultaneous data acquisition of the light and the current intensities were performed in LabVIEW6.1. The CL reagents and the sample were first aspirated as distinct zones into the holding coil of the analyser and, then, delivered to the cell; during their travel, the individual zones mixed and the ECL reaction was initiated as soon as the mixed regents reached the cell. The utility of the analyser was demonstrated for the detection of oxalate andH2O2based on their ECL reactions withRu(bpy)32and luminol, respectively.
