Quantitative ultraviolet measurements on wetted thin-layer chromatography plates using a charge-coupled device camera [PDF]

, 2008
This paper presents the first study of the UV imaging of spots on thin-layer chromatographic plates whilst still wet with solvent. Imaging of spots of benzophenone during and after development was carried out using a charge-coupled device camera.
