      A new retention model for RPTLC with (B + AB)-type mobile phases
      A. PODGORNY, (Inst. of Chem., Silesian Univ., 9 Szkolna Str., 40-006 Katowice, Poland)

      J. Planar Chromatogr. 8, 336 - 340 (1995). Introduction of a new model of solute retention for RPTLC with (B + AB)-type mobile phase. On the basis of theoretical assumptions physico-chemical relationships were derived for solute Rf values in RPTLC with acetonitrile - water, tetrahydrofuran - water, and acetone - water. The practical utility of the model has been demonstrated with abundant experimental results. Excellent agreement was observed between experimental and predicted Rf values for test solutes. - RPTLC of naphthalene, anthracene, phenanthrene, chrysene, and pyrene on RP-18 silica developed with ACN - water, THF - water, and acetone - water mixtures of different ratios.

Detection at 254 and 366 nm. Quantitative fluorescence measurement at different excitation wavelengths with cut-off filters: 220 nm/>320 nm for ACE, 250/>320 for ANT, 366/>400 for BAA and BAP, 270/>400 for BBF, BPE, BKF, CHR, DBA, FLA, IDN (after dipping in nitromethane), 250/>320 for FLU and PHE and at 270/>320 for PYR. Polynomial regression with high coefficients of correlation and low standard deviations. Coeffivients of variation for repeatability and reproducibility were below 10 %. This method allows the determination of 14 of the 16 PAHs. With LODs of 0.1-0.2 mg/kg the demands for the German GS mark (label for checked safety) are fulfilled. The results by HPTLC were comparable to results obtained by GC-MS.
