J. Liq. Chromatogr. Relat. Technol. 31, 1925-1942 (2008). HPTLC of benzo[a]pyrene, benzo[b]fluoroanthene, benzo[k]fluoroanthene, benzo[ghi]perylene, fluoroanthene, 2-methylanthracene, and indeno[1,2,3-cd]pyrene on silica gel impregnated with caffeinesolution (by dipping in a solution of 2 g caffeine in 120 mL acetonitrile for 20 min, followed by drying for 15 min at 120 °C) with isopropyl acetate - acetonitrile 7:3 in a twin trough chamber at -20 °C. For fluorescence enhancement the plates were dipped in a solution of paraffin - n-hexane 1:1 and dried for 1 min in cold air. Quantitative determination by fluorescence measurement at 366/>400 nm. The method can be applied for control of the limit levels of the six polycyclic aromatoc hydrocarbons in water. The limits of quantitation were 0.08-0.44 ng/band depending on the substance. Linearity showed coefficients of correlation = 0.9920. The recoveries by stir bar sorptive extraction (n = 3) were between 87-100 % depending on the substance. The whole procedure was optimized to reach a sample throughput of 30 water samples, inclusive sample preparation by stir-bar sorptive extraction (SBSE), per 8-hour day.

CBS 83, 6-7 (1999). HPTLC-AMD of PAHs in liver and lung of animals exposed to contaminated soil on RP-18 with a 14-step gradient from acetonitrile to methanol - water 9:1. Quantification by fluorescence measurement at 313/>400 nm and 254/>400 nm, respectively. Strict linearity (r2 > 0.99 on 5 measuring points) was proven. Coefficient of variation was found to be < 5 %, and recoveries between 55 and 70 % were given. Limits of detection was determined to be 0.2 to 2 ng/g sample.
