Abstract: A multi-channel detector which can simultaneously monitor more than one flow-cell at multiple wavelengths for multi-component analysis has been developed. The detector contains up to four flow-cells each equipped with dual wavelength light-emitting diodes (LED) and photo transistors as light source and detector. The LED are switched on and off under computer control and the light measured by the photo transistor and amplifier. The absorbance for each wavelength and cell was calculated by a single-chip microcomputer. The absorbance of a 1 x 10^-5 g/ml bromothymol blue solution was measured at 630 nm and 565 nm with a RSD of 0.25% and 0.24% respectively. The performance was demonstrated from the simultaneous determination of Co and Cd in zinc sulfate electrolyte, producing comparable results to those obtained by traditional methods.
