Fig. 6From: Colorimetric sensor array for versatile detection and discrimination of model analytes with environmental relevanceThe LDA results among seven investigated bases with concentrations 1.0, 0.7, 0.5, 0.3, 0.1, 0.05, 0.01, and 0.001 mol L−1. The colorimetric response for given concentrations (4 sensing elements × 3 colorimetric channels × 7 type of bases × 3 replicates) were analyzed by LDA in IBM SPSS 22.0 software and results were shown in this figure. No overlap, which indicated that the bases could be discriminated in concentrationsBack to article page
