Review of the following topics for the period of November 1, 2016 to November 1, 2018: sample preparation for TLC pesticide analysis; lipophilicity and retention studies for the study of biological activity; new reagents for pesticide detection; HPTLC-effect directed analysis on the surface of the layer; TLC-Raman spectrometry for the analysis of thiabendazole, triazophos, and phosmet residues; TLC analysis of radiolabeled pesticides; methods for the separation, detection, and qualitative and quantitative determination of pesticide residues; determination of pesticides in commercial products and the use of TLC for pesticide degradation studies.

      CBS 98, 9-11 (2007). Quantitative HPTLC of polycyclic aromatic hydrocarbons (PAH) from water samples, on caffeine-impregnated silica gel, with isopropyl acetate in a precooled (-20 °C, 30 min) twin-trough chamber without chamber saturation over 70 mm at -20°C. After application the dry plate was first equilibrated in the solvent-free trough for 10 min at -20 °C. Qualitative HPTLC at room temperature in the horizontal developing chamber with isopropyl acetate - n-hexane 3:1 over 50 mm. Detection by dipping in paraffin - toluene 1:1 (for fluorescence enhancement). Quantitative determination by fluorescence measurement at UV 366/>400 nm. Qualitative evaluation under UV 366 nm. The method is based on the German standard DIN 38407-7 for quantitative determination of 6 PAH but uses isopropyl acetate as a chlorine-free solvent instead of dichloromethane.

      M. GÖCER, K. HOFERER, J. ZIPFEL, B. SPANGENBERG* (*University of Offenburg, Institute of Process Engineering, Badstrasse 24, 77652 Offenburg, Germany; Spangenberg@FH-Offenburg.de)

      J. Planar Chromatogr. 22, 59-63 (2009). HPTLC of paraquat, diquat, difenzoquat, mepiquat, and chloromequat on LiChrospher silica gel with 1-propanol - methanol - 2.5 M aqueous sodium chloride 1:1:3. Detection by immersion for 2 s in a solution of 50 mg sodium tetraphenyl borate in 50 mL of water containing 50 µL concentrated hydrochloric acid. The wet plate was illuminated for 5 min with UV light at 254 nm which resulted in the formation of fluorescing spots corresponding to mepiquat, chloromequat, and difenzoquat. Immediately after illuminating at 254 nm all spots were illuminated for 10 min with UV light at 365 nm, which converted all compounds into fluorescent derivatives. Then the dry plate was dipped into ethylene glycol - methanol 1:1 for 2 s, which enhanced the fluorescence by a factor of two. Detection by fluorescence measurement and averaged densitograms were obtained in the emission wavelength range from 440 to 480 nm.

      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.
