Chinese J. Chromatogr. (Sepu) 9, 124-126 (1991). TLC of N-(a-pyridyl)-carbazole on silica with cyclohexane - 1,2-dichloroethane 1:1. Detection under UV. Quantification by densitometry at 285 nm using external standards. CV = 1.9 - 7.4%.
J. Planar Chromatogr. 12, 228-229 (1999). TLC of rapeseed oil, rapeseed methyl esters and crankcase lubricants on silica gel with hexane - diethyl ether - acetic acid 85:15:1 or hexane - ether 4:1. Detection by spraying with a 1:1 mixture of saturated copper acetate in water and 85% orthophosphoric acid, followed by heating at 180°C for 7 min. Quantitation by desitometry at 510 nm.
J. Chromatogr. 318, 75-84 (1985). Reversed-phase 2-dimensional TLC of epoxy resins on octadecyl silanized silica with acetonitrile - water 7:3. for the first dimension and chloroform for the second. Detection by UV 254 nm. Comparison to reversed-phase LC. TLC found advantageous due to time requirements and cost-effectiveness.
J. Chromatogr. Sci. 36, 91-96 (1998). HPTLC on silica gel with chloroform - methanol - water 80:19:1. Detection by spraying with 5% sulfuric acid in ethanol and heating at 100°C for 5 min. Comparison with HTHR GC and NMR.
J. Chromatogr. A 1218 (19), 2785-2792 (2011). Examination of the applicability of TLC for the analysis of biodiesel conversion. Biodiesel is a complex mixture which complicates the analytical separation and requires a large set of data for understanding reaction kinetics. A flame ionization detector (FID) and a modified TLC staining procedure were evaluated in comparison with the well-established but time-consuming and expensive GC and HPLC methods. The TLC staining method is suited for quantitative analysis due to no background. Demonstration by using several experimental samples produced by enzymatic conversion of rapeseed oil to biodiesel. It was found that the first reaction step (6 h) resulted in 85–95 % conversion and the second step (after removal of glycerol and water) increased the yield to 97–98 %. All components of the mixtures were separated and quantified. Relation of the biodiesel contents measured by TLC and GC gave the values of 1.03 ± 0.07 (TLC-staining) and 0.95 ± 0.04 (TLC–FID), which indicated the applicability of the TLC methods.
Deut. Lebensm. Rundschau 91, 205-208 (1995). HPTLC of optical brighteners (Leucopur, Azur 4, Azur 5, Hostalux ABC, Uvitex, Eastobrite) on RP-18 with acetonitrile - dichloromethane 19:1, acetonitrile - water 19:1 and methanol - water 97:3. The organic mixture showed better separation than the aqueous phases. Detection under UV.
J. Planar Chromatogr. 26, 96-101 (2013). HPTLC of cetylpyridinium chloride (1), sodium dodecyl sulfate (2) and Triton X-100 (3) on silica gel with methanol - water 1:1. Quantitative determination by absorbance measurement at 254 nm. The hRf values for (1) to (3) were 6, 74 and 91, respectively. Linearity was in the range of 170-1740 µg/zone for (1), 250-1980 µg/zone for (2) and 160-1640 µg/zone for (3). LOQ was 75 ng/zone for (1), 90 ng/zone (2) and 65 ng/zone for (3).
J. China Assoc. Inst. Anal. 6, 19-22 (1987) (Fenxi Ceshi Tongbao). TLC on silica with chloroform - methanol - acetic acid - water 80:10:8:2. Detection by exposing to iodine vapour. Quantification by densitometry at 520 nm.
