J. AOAC Int. 93, 1757-1767 (2010). HPTLC of four mixtures of 21 pesticides on RP-18 by PPEC under different operating conditions. The samples were separated on a prewetted RP-18 phase with acetonitrile - buffer. Detection under UV light at 254 or 366 nm and in the range of 197 to 1033 nm with a DAD densitometer. Reproducible retention of pesticides was obtained; the reported separations are over 10 times faster than the corresponding separations by TLC.

J. Liq. Chromatogr. Relat. Technol. 37, 2846-2856 (2014). HPTLC fingerprinting of materials originated from cold surfaces of biomass fuel and fossils-fired home heating ovens, as well as truck exhaust systems and asphalt concrete samples on RP-18 with n-hexane. Fluorescence detection at UV 366 nm and absorbance detection (fluorescence inhibition) at UV 254 nm. The method can be used to identify wrong combustion parameters or unsuitable fuel.

CBS 114, 13-15 (2015). To test the new HTpSPE–TOFMS screening, TLC of a pesticide mixture (acetamiprid, azoxystrobin, chlorpyrifos, fenarimol, mepanipyrim, penconazole, pirimicarb) in several plant matrices (cucumber, tomato, grape, apple extracts) on amino layer pre-treated by dipping in 2 % formic acid solution in acetonitrile and drying for 10 min. Development with 10 mL acetonitrile, migration distance 75 mm, drying 5 min; second development in the backwards direction with 10 mL acetone, migration distance 45 mm, drying 3 min. Detection under UV 254 nm, UV 366 nm and white light. For HTpSPE and μL-flow injection analysis–TOFMS the target analyte zone was eluted with the TLC–MS Interface into autosampler vials with acetonitrile – 10 mM ammonium formate 1:1, flow rate 0.2 mL/min, Elution time was 60 s. An HPLC system was coupled via a PEEK capillary and a nano-electrospray ionization interface to a TOFMS without an analytical column. The mean recovery for a pesticide mixture spiked into fruit and vegetable extracts was between 86 % and 116 % with %RSDs of 1.5–10 % (n = 5).

J. Chromatogr. A 1526, 151-156 (2017). Development of a rapid and cost-effective method for determining brominated flame retardants (BFR) such as tetrabromobisphenol A/S (TBBPA/S) and their derivatives in soils, including TBBPA, TBBPA bis(allyl ether) (TBBPA-BAE), TBBPA bis(2,3-dibromopropyl ether) (TBBPA-BDBPE), TBBPS bis(allyl ether) (TBBPS-BAE) and TBBPS bis(2,3-dibromopropyl ether) (TBBPS-BDBPE), based on TLC sample pre-treatment coupled with HPLC-DAD at UV 214 nm. The LODs and LOQs were between 0.023-0.087 μg/g dw and 0.076-0.29 μg/g dw, respectively. The recoveries were between 41-108 % and both % RSD of repeatability and intermediate precision were < 11 %. The method showed a good performance for analyzing natural soil samples collected from BFRs industrial park, suggesting its great application potential for monitoring environmental TBBPA/S and their derivatives.
