Fig. 2From: Colorimetric sensor array for versatile detection and discrimination of model analytes with environmental relevanceTotal EDs versus concentration curves for each organic compound at the concentration range of 0.001–1.0 mol L−1 Feasibility of quantitative analysis using sensor array. Overall sensor response for each analytes (i.e., ED from the changes in all RGB values from 4 sensor elements) versus concentration were shownBack to article page
