J. Planar Chromatogr. 6, 112-116 (1993). The use of the colorimeter for standardization of color measurement in thin-layer chromatography, and the handling of the data obtained, have been evaluated. The identification power, expressed as the mean list length (MLL), was 8.32 and 6.34 for visual and colorimetric methods, respectively. When fluorescence measurements were included in the encoding system, the MLL obtained from visual coding dropped dramatically to 2.90. The colorimeter tested was not able to measure UV reflection.
