Abstract

A portable device for colorimetric or fluorometric analysis comprises a linear array of optically-responsive chemical sensing elements; an image sensor in optical communication with the linear array for determining a spectral response of the optically-responsive chemical sensing elements, where the image sensor comprises at least one light emission source; and electronics connected to the image sensor for analyzing spectral response data. A method of conducting colorimetric or fluorometric analysis comprises exposing a linear array of optically-responsive chemical sensing elements to a fluid comprising an analyte; impinging light on the linear array and detecting a spectral response of the chemical sensing elements; and determining an exposed color of each of the chemical sensing elements.
