Abstract

A low cost, highly sensitive optical device was constructed with an array of LED emitter and a single LED light detector for colorimetric analysis. Enhanced selectivity for a specific chromophore was obtained by choosing LEDs with emission bands that overlap with its absorption band. This multi-sensor approach coupled with statistical technique PCA was demonstrated to discriminate between various single-dye samples and to resolve complex colour mixtures.
