Abstract
A simple and rapid TLC - videodensitometric method has been developed for the in situ quantification either of lower halogenated subsidiary colors (LHSC) or of the ethyl ester (EE) in multiple dye samples on th e same analytical TLC plate. The results obtained by this method were compared with those obtained by an indirect TLC - spectrophotometric m ethod and those obtained by HPLC. The total time for the TLC - videode nsitometric assay of five standards and four samples applied to each p late was 45 min or less. This method for the determination of LHSC and EE in D&C Red Nos. 27 and 28 was found to be applicable for use in ro utine batch-certification analysis.
