J. AOAC Int. 92, 1153-1159 (2009). HPTLC of sucralose on amino phase with acetonitrile - water 4:1 in a horizontal or standard development chamber without chamber saturation. For detection the plate was heated at 190 °C for 20 min, either in a drying oven or on a temperature-controlled heating plate. Quantitative determination by absorbance and fluorescence measurement at 254 nm. The results of the interlaboratory comparison show good precision characteristics. The fluorescence measurements of the sucralose derivatives indicated better method performance, compared with absorbance measurements in the UV.
