      Food Chem. 416, 135822 (2023). A chip consisting of two parts: a pesticide residue reaction and a separation area cut from a TLC plate was used for the analysis of pesticides dichlorvos, paraoxon and parathion in spiked cabbage, cucumber and spinach with 40 % dd water - acetonitrile solution. Once the pesticide was absorbed by the pesticide enrichment zone, the TLC plate was removed and allowed to dry in the air for 1 min, followed by adding the esterase enzyme solution (prepared from crushed malted barley) and incubation at 37 °C for 3 min. Detection by overlapping with a substrate cromogenic area impregnated with dichloroindophenol acetate. A scanner and digital image-processing was performed to quantify adsorbed substances. LOD was 2 ng/g for dichlorvos, 6 ng/g for paraoxon, and 3 ng/g for parathion.

      Identification of acetylcholinesterase inhibitors in water by combining two-dimensional thin-layer chromatography and high-resolution mass spectrometry
      Lena STÜTZ*, W. SCHULZ, R. WINZENBACHER (*Laboratory for Operation Control and Research, Zweckverband Landeswasserversorgung, Langenau, Germany; stuetz.l@lw-online.de)

      J Chromatogr A, 1624, 461239 (2020). Samples were chemical standards of acetylcholinesterase (AChE) inhibitors (azamethiphos, caffeine, donepezil, galanthamine, methiocarb-sulfoxide, paraoxon-ethyl) and of neurotoxic compounds, as well as drinking or contaminated water samples enriched through solid phase extraction. HPTLC on spherical silica gel (pre-washed twice by 20 min immersion in isopropanol, heated 20 min at 120 °C before and after pre-washing with acetonitrile). First separation (preparative TLC) with automated multiple development (16 steps). Effect-directed analysis for AChE inhibitors by immersion (speed 5 cm/s, time 1 s) into enzyme solution, incubation 5 min at 37 °C and immersion into substrate solution (indoxyl acetate 2 % in methanol); visualization under UV 366 nm. Active zones from untreated layers were eluted through the oval head of a TLC-MS interface to a second plate for a second separation with a panel of other mobile phases. Bands of interest were eluted from the second layer with water through the oval elution head of the TLC-MS interface pump, into a RP18 liquid chromatography guard column, followed by a quadrupole time-of-flight mass spectrometer. Full scan mass spectra (m/z 100–1200) were recorded in negative and positive modes using electrospray ionization (and collision-induced dissociation for MS2). Among the water contaminants, lumichrome (riboflavin photolysis product), paraxanthine and linear alkylbenzene sulfonates were identified as AChE inhibitors.
