      Validation of an HPTLC method for determination of caffeine
      I. VOVK, A. GOLC-WONDRA, M. PROSEK*, (*Nat. Inst. of Chem., Lab. of Food Chem., Hajdrihova 19, 1000 Ljubljana, Slovenia)

      J. Planar Chromatogr. 10, 416-419 (1997). Complete validation of an HPTLC method for the quantitative determination of caffeine in Coca-Cola has been performed according to ICH guidelines, taking into consideration the special features of the method. The validation parameters were: selectivity, stability of the analyte, linearity, precision, (repeatability and intermediate precision), and robustness. Quantification with a slit-scanning densitometer and with an image-analyzing system. The same plates were used in both validation procedures to reveal possible differences between the different modes of quantification. The results obtained show no difference in validation parameters - because all the results are within the range of criteria recommended for TLC validation. Both systems can be used for quantitative evaluation of TLC plates.
