      Quantitative measurements on wetted thin layer chromatography plates using a charge coupled device camera
      M. LANCASTER*, D.M. GOODALL, E.T. BERGSTROEM, S. MCCROSSEN, P. MYERS (*Department of Chemistry, University of York, York YO10 5DD, United Kingdom)

      J. Chromatogr. A 1090 (1-2), 165-171 (2005). This paper presents the first study of imaging of spots on thin-layer chromatographic plates whilst still wet with solvent. Imaging and quantification of Sudan II after development with dichloromethane was carried out in both reflectance and transmission modes, using a charge coupled device (CCD) camera. The relationship between peak area and sample loading was established at low sample loading, and found to be linear over an order of magnitude for both wet and dry modes with r2-values > 0.99. All data processing was carried out using the Beer-Lambert equation. Curvature at high loadings in the plots of integrated absorbance as a function of sample loading was accounted for using an empirical expression designed for use with the Kubelka-Munk treatment and apparent absorbance of the stationary phase due to scattering. Results are consistent with an effective pathlength significantly longer than the thickness of the sorbent layer. The limit of detection on a dry plate (0.5 ng) was found to be lower than on a wetted plate (2 ng). Precision was found to be 1-4 % RSD intra-plate and 8-14 % RSD inter-plate. Results are compared with quantification of the same analyte on dried plates.

      Densitometric determination of some bioactive guanidinium compounds without post-derivatization
      A. Szabo, B. Erdélyi*, J. Salát, G. Máté (*Fermantation Pilot Plant, IVAX Drug Research Institute, Berlini u. 47-49, 1049 Budapest, Hungary)

      J. Planar Chromatogr. 18, 203-206 (2005). TLC of primycin (a mixture of related compounds), streptomycin, dihydrostreptomycin on silica gel with A) n-butanol - water - methanol - acetic acid 4:2:1:1; and B) chloroform - methanol - water - 35% formic acid - n-butanol - formaldehyde 160:53:9:6:3:3. When using phase B repeated development improved the resolution. After development the plates were dried in a vacuum chamber at 100 °C. An efficient prewashing technique (with methanol - 35 % formic acid 1:1 followed by drying with hot air) made the TLC plates suitable for densitometric measurements at short wavelengths. Quantitative determination by absorbance measurement at 200 nm.
