      J. Planar Chromatogr. 31, 272-279 (2018). HPTLC of chlorpheniramine (1), pseudoephedrine (2), and ibuprofen (3) on silica gel with ethyl acetate ‒ methanol ‒ ammonia 20:5:2. Quantitative determination by absorbance measurement at 262 nm. The hRF values for (1) to (3) were 78, 64 and 29, respectively. Linearity was between 0.2 and 9 μg/zone for (1), 2 and 30 μg/zone for (2), and 5 and 50 μg/zone for (3). LOD and LOQ were 72 and 218 ng/zone for (1), 285 and 864 ng/zone for (2), and 1004 and 3042 ng/zone for (3), respectively. The intermediate precision was <2 % (n=3). Average recovery was 100.5 % for (1), 100.9 % for (2) and 100.7 % for (3).

      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.

HPTLC of cinchocaine hydrochloride from suppositories on silica gel with 1-butanol - toluene - ethanol - water - 100 % acetic acid 10:8:7:4:1 over 30 mm followed by heating at 110 °C for 10 min. Quantitative determination by fluorescence measurement at 313/>400 nm.Precision is 2 % and recovery 101 %.

      Analytical uncertainty in modern quantitative TLC
      M. PROSEK*, A. GOLC-WONDRA, T. MAVER, M. FIR (* National Institute of Chemistry, Hajdrihova 19, 1000 Ljubljana, Slovenia)

      J. Planar Chromatogr. 17, 102-108 (2004). For sample preparation a methanolic salicylic acid solution was sprayed onto a 40x40 cm glass plate. Samples from different positions of the test plate were extracted with methanol and analyzed by HPTLC and HPLC. HPTLC of salicylic acid on silica gel with cyclohexane - isopropanol - chloroform - acetic acid 12:1:1:2. Quantitation by densitometry. Measurement uncertainty in HPTLC and HPLC is relatively small and has no effect on recovery. To come close to the true value the analytical procedure must be managed by well-considered selection of number and positions of sampling locations. TLC is an excellent analytical technique which gives reliable results.

      J. Planar Chromatogr. 17, 420-423 (2004). A new on-line TLC-MS interface, with computer-controlled extraction of substances from selected spots on a TLC or HPTLC plate, has been constructed. The controlled collection of the sample and its programmed injection into the mass spectrometer is the advantage of this type of interface. It has been tested and validated with a standard solution of caffeine as test substance. HPTLC of caffeine on silica gel with dichloromethane - methanol 9:1. Quantification with a video-documentation system.
