The ChromImage flatbed scanner densitometer with Galaxie-TLC software has been used for quantification of silica gel high-performance thin-layer chromatography (HPTLC). The visible mode was evaluated by determination of the recovery of a rhodamine B standard dye from a fourdye mixture and by determination of the precision of replicate analysis. Determinations of caffeine in multicomponent analgesic tablets and a cola beverage were performed in the fluorescence-quenching mode. Previously published methods for the tablet and beverage analyses were modified by using HPTLC plates with a brilliant ultraviolet indicator, and analysis of the beverage was further modified by automated application of standard and sample bands by use of a Linomat. Accuracy, precision, linearity, and sensitivity of these analyses with the ChromImage are reported.
