J. Liq. Chromatogr. Relat. Technol. 39, 271-276 (2016). HPTLC of ziprasidone and its impurities on silica gel with toluene – methanol – glacial acetic acid 15:1:1. Quantitative determination by absorbance measurement at 250 and 320 nm. The hRF value was 42 for ziprasidone and 19, 28, 31, 58 and 70 for its impurities. LOQ of impurities was 25 ng/zone. Recovery was between 94.9 and 106.7 %. See also J. Planar Chromatogr. 29, 239-246 (2016).

Quantitative determination by absorbance measurement at 215 nm. The hRF values for (1) to (4) were 29, 56, 67 and 75, respectively. Linearity was between 400 and 2000 ng/zone for (1), 200 and 1500 ng/zone for (2), 1000 and 7000 ng/zone for (3) and 300 and 1500 ng/zone for (4). LOD and LOQ were 83 and 252 ng/zone for (1), 54 and 164 ng/zone for (2), 156 and 474 ng/zone for (3) and 77 and 234 ng/zone for (4), respectively. The intermediate precision was <3 % (n=6). Recovery rate ranged from 99.3 to 100.9 % for (1-4).
J. Planar Chromatogr. 31, 290-296 (2018). HPTLC of sulfadoxine (1), sulfalene (2), and_x000D_ pyrimethamine (3) on silica gel with toluene - ethyl acetate - methanol 100:56:43. Quantitative determination by absorbance measurement at 254 nm. Linearity was between 1 and 3 μg/zone for (1) and (2), and 0.05 and 0.15 μg/zone for (3). LOD was 0.107 ng/zone for (1), 0.04 ng/zone for (2) and 1.62 ng/zone for (3), and LOQ was 0.32 ng/zone for (1), 0.13 ng/zone for (2) and 4.92 ng/zone for (3). The intermediate precision was <4 %. Average recovery was 98.0 % for (1), 97.2 % for (2) and 101.8 % for (3).
J.A.O.A.C. 67, 934-939 (1984). TLC of xanthone, propantheline, xanthonoic acid, 9-hydroxy propantheline, methyl xanthanoate, methyl 9-hydroxy-xanthanoate on silica with 1,2-dichloroethane - methanol - formic acid 80:20:2 and 1,2-dichloroethane - methanol 98:2. Detection by UV 366 nm.
J. Chromatogr. Sci. 22, 538-547 (1984). Principal component analysis (PCA) with Rf values for 596 basic and neutral drugs in 4 eluent mixtures on silica. Two-component model explaining 77 % of the total variance. Each drug is characterized on a plane by two principal component scores. For the identification of unknowns the method provides a drastically reduced short list of possible candidates. The 4 eluent systems are: a) methanol - NH3 100:1.5, b) cyclohexane - toluene - diethylamine 75:15:10, c) chloroform - methanol 9:1, d) acetone.
