      Open-source add-on kit for automation of zone elution in planar chromatography
      T. HÄBE, Gertrud MORLOCK* (*Justus Liebig University Giessen, Heinrich-Buff-Ring 26–32, 35392 Giessen, Germany, gertrud.morlock@uni-giessen.de)

      Rapid Commun. Mass Spectrom. 34, 8631 (2020). A 3D-printed, fully automated, open-source add-on user interface was built for elution-head-based TLC/HPTLC-MS. The system allowed a very compact plate-positioning system combined with an image-based software solution providing a platform to control and synchronize all steps from positioning, elution, advanced cleaning to MS data acquisition.

      Comprehensive HPTLC fingerprinting: A novel economic approach to evaluating the quality of Ganoderma lucidum fruiting body
      Débora FROMMENWILER*, D. TREFZER, M. SCHMID, S. CAÑIGUERAL, E. REICH (*Unit of Pharmacology, Pharmacognosy and Therapeutics, Faculty of Pharmacy and Food Sciences, University of Barcelona, Av. Joan XXIII, 27-3, ES-08028 Barcelona, Spain, debora.frommenwiler@camag.com)

      J. Liq. Chromatogr. Relat. Technol. 43, 414-423 (2020). HPTLC fingerprint of Ganoderma lucidum fruiting body on silica gel with toluene - tetrahydrofuran - acetic acid 70:30:1. Detection by dipping into a solution of 10% sulfuric acid in methanol, followed by heating at 100 ºC for 3 min. Qualitative determination under UV light at 254 and 366 nm. The hRF values for ganoderic acids D, B, A, G and C2 were in the zone between 10 and 50. This zone was used for quantification of total triterpene acids by absorbance measurement at 260 nm. Linearity of each of the main peaks between hRF 10 to 50 was determined. The linear range of ganoderic acid A was between 200 and 500 ng/zone.  The study proposes a new method for evaluation, based on “comprehensive high-performance thin layer chromatography (HPTLC) fingerprinting.” Instead of several different methods using different chromatographic techniques, a single HPTLC analysis for identification of Ganoderma lucidum fruiting body with a test for adulteration and quantitative determination of the content of total triterpene acids is proposed. As an alternative to the current tests in the  USP monograph on G. lucidum fruiting body this HPTLC method is a single, low-cost test, which eliminates the UHPLC assay of total triterpene acids.

      Strategy for separation of complex mixtures by multidimensional planar chromatography
      T. TUZIMSKI (Medical University of Lublin, Faculty of Pharmacy, Department of Physical Chemistry, Staszica 6, 20-081 Lublin, Poland; tomasz.tuzimski@am.lublin.pl)

      J. Planar Chromatogr. 21, 49-54 (2008). Report of a new procedure for separation of complex mixtures by combining different modes of multidimensional planar chromatography on silica gel plates. Initially the complex mixture was separated into five groups of compounds. Mobile phases for separation of these different groups were then optimized by regarding each group as individual separation problem. By use of this new procedure 22 compounds from a complex mixture were separated on 10 x 10 cm TLC and HPTLC plates. TLC and HPTLC of 22 pesticides on silica gel with ethyl acetate - n-heptane 2:3 for TLC and 1:1 for HPTLC in the first direction. After removal of some of the adsorbent layer five further development steps with different eluents followed resulting in the complete separation of the 22 compounds of interest . Detection under UV 254 and 366 nm.

      Attenuated total reflectance as an alternative of diffuse reflectance infrared detection in the identification of compounds separated by thin layer chromatography
      D. SZIKRA*, I.P. NAGY (*Department of Physical Chemistry, University of Debrecen, Hungary; deeezs@yahoo.com)

      J. Liq. Chromatogr. Relat. Technol. 31, 161-168 (2008). TLC of 37 compounds, i. a. nitrotoluene, on silica gel, aluminium oxide, cellulose, and silanized silica gel after a short (few centimeters) elution with different eluents. After precise positioning, attenuated total reflectance (ATR) is used for measuring the spots against air background in the range of 650-4000/cm. Diffuse reflectance (DRIFT) and ATR are infrared sampling methods, based on the detection of infrared radiation reflected by the sample. They are widely used in surface analysis and are both capable of detecting small amounts of organic compounds. DRIFT is a well known on-layer method for the identification of analytes, separated on thin layers. In the present work, the possibility of using a diamond ATR unit to collect IR spectra of sample spots is examined.

      New interfaces for coupling TLC with TOF SIMS
      A. ORINAK*, H. F. ARLINGHAUS, G. VERING, M. JUSTINOVA, R. ORINAKOVA, L. TURCANIOVA, M. HALAMA, (*Univ. of P. J. Saf·rik, Inst. of Chem. Sci., Dept. of Physical and Anal. Chem., Moyzesova 11, 040 01 Kosice, Slovakia)

      J. Planar Chromatogr. 16, 23-27 (2003). TLC of a zinc complex stock solution (Zn(CH3CH2COO)2(tu)2 - a complex of zinc butyrate bound to two thiourea molecules) on RP-18, aluminium backed, with methanol - water 2:3. The first interface was formed by vacuum deposition of silver on to the chromatographic layer and onto a channel formed by scraping the layer from the glass plate. The unmodified aluminium backing of a TLC plate (again formed by elution) was used as the second interface. Silver vapor-coated aluminium gave better results.
