Exposure to pyridine for 20 min, followed by irradiation (6 min) by long-wave UV light. Quantification by fluorodensitometry at 420 nm excitation and 550 nm emission. Detection limit 1 ng. Calibration curve was found linear from 2.5-30 ng. Recoveries 87.1-88.7 %.
J. Planar Chromatogr. 11, 433-437 (1998). Examination of the behavior of some dihydroxybenzanilides, organic compounds with fungicidal properties, using RP-planar chromatography. The effect of organic modifier (methanol or acetone) concentration and stationary phase (RP-NH2 or RP-CN) properties on solute retention was investigated and the dependence of peak shape and symmetry on the mobile and stationary phase was analyzed. RP-CN phases are useful for the chromatographic separation of benzanilides chosen. Chromatography was performed at 20°C in a horizontal sandwich chamber saturated for 20 min. Densitometry at 325 nm.
A new approach in forensic analysis. J. Planar Chromatogr. 24, 108-112 (2011). HPTLC of ditalimfos, edifenfos, and tolclofos-methyl on silica gel, prewashed with methanol, with n-hexane - acetone 9:1 in a twin-trough chamber with saturation. Quantitative determination by densitometry in absorbance mode at 254 nm, the wavelength of maximum absorption for all three fungicides. The hRf values of all three organophosphorus fungicides increased with increasing contents of acetone in the mobile phase.
Pharmazie 42, 356 (1987). TLC of Rotenoids (terphrosin, sumatrol, rotenone, deguelin, dehydro-deguelin) on silica with chloroform - ether 95:5 or with chloroform - ethyl acetate - acetic acid 196:3:1. Vizualisation by spraying with hydroiodic reagent and heating at 120°C for 20 min.
J. Planar Chromatogr. 4, 106-110 (1991). Presentation of 3 examples of optimization of AMD gradients: 1 + 2: Universal gradients optimized for the separation of phenolic compounds spanning a wide polarity range on diol layers, 3: Optimization for the separation of organochlorine pesticides on silica spanning a low polarity range. Preliminary isocratic developments of selected standards were performed with binary solvent mixtures in order to set up the gradients. The retention data (as plots of Rm values against solvent composition) can be used for the choice of the gradient components and gradient boundaries.
J. AOAC Int. 82, 785-791 (1999). Analytical and preparative TLC of fenpropathrin [(R,S-a-cyano-3-phenoxybenzyl-2,2,3,3-tetramethylcyclopropane carboxylate] and fluvalinate [a -cyano-3-phenoxybenzyl-2,2-dichloro-4-(trifluormethyl)anilino)-3-methyl butanoate] on silica gel with hexane - acetone 9:1; chamber saturation. Detection by spraying with potassium permanganate - sulfuric acid. Quantitation after elution by spectrophotometry.
J. Sep. Sci. 31, 3537-3542 (2008). After solid phase extraction of water samples HPTLC of clofentezine (1), neburon (2), chlorfenvinphos (3), lenacyl (4), trifluralin (5), thiram (6), procymidone (7), flufenoxuron (8), tralkoxydim (9), propaquizafop (10), and dinoseb (11) on silica gel with ethyl acetate – n-heptane 2:8, 3:7, 4:6, or 7:3 as mobile phase. Quantitative determination by absorbance measurement between 200 and 600 nm. Selectivity regarding matrix was given. Linearity was 0.1-1.5 µg/spot for (1), 0.2-1.0 µg/spot for (2), 0.5-1.0 µg/spot for (3), 0.2-1.0 µg/spot for (4), 0.3-9.0 µg/spot for (5), 0.2-1.0 µg/spot for (6), 2.0-11.0 µg/spot for (7), 0.1-2.0 µg/spot for (8), 0.3-1.0 µg/spot for (9), 0.1-1.0 µg/spot for (10), and 0.2-1.0 µg/spot for (11). The limits of detection and quantification were 0.23 and 0.70 µg/spot for (1), 0.06 and 0.18 µg/spot for (2), 0.16 and 0.49 µg/spot for (3), 0.04 and 0.12 µg/spot for (4), 0.06 and 0.18 µg/spot for (5), 0.16 and 0.49 µg/spot for (6), 0.65 and 1.92 µg/spot for (7), 0.10 and 0.31 µg/spot for (8), 0.07 and 0.22 µg/spot for (9), 0.06 and 0.17 µg/spot for (10), and 0.08 and 0.24 µg/spot for (11).
