J. of Chromatogr. A 1218 (37), 6540-6547 (2011). New approach and application of highly automated planar chromatographic tools for powerful clean-up, called high-throughput planar solid phase extraction (HTpSPE), which is indispensable for preventing matrix effects in multi-residue analysis of pesticides in food by liquid and gas chromatography coupled to mass spectrometry, employing TLC to completely separate pesticides from matrix compounds and to focus them into a sharp zone, followed by extraction of the target zone by the TLC-MS interface, thus resulting in extracts nearly free of interference and free of matrix effects, as shown for seven chemically representative pesticides in four different matrices (apples, cucumbers, red grapes, tomatoes), and completion of clean-up of one sample in a manner of minutes. Regarding the clean-up step, quantification by LC–MS with mean recovery (against solvent standards) of 90–104% and relative standard deviations of 0.3–4.1% (n = 5) for two spiking levels of 0.1 and 0.5 mg/kg.

J. Chromatogr. Sci. 46 (4), 308-315 (2008). Investigation of the usefulness of flux calcinated diatomaceous earth (FCDE-I) (modified from natural diatomaceous earth and characterized by microscopical, physical, and chemical analyses) as a sorbent material for TLC. TLC of sodium diethyldithiocarbamate (DEDTC) and ammonium pyrrolidinedithiocarbamate (PyDTC) as Co or Cu complexes on silica gel and FCDE-I layer individually, and on various FCDE-I and silica gel mixtures. Development with toluene, toluene - cyclohexane 3:1, 1:1, 1:2, 1:3. The best separations were obtained with pure toluene, toluene - cyclohexane 3:1, and 1:1 respectively, using layers of FCDE-I - silica gel 1:3, and 1:1 respectively. Qualitative analysis of mixtures of Cu2+ and Co2+ cations is possible with the same system.
