      High performance thin-layer chromatography (HPTLC) - A versatile technique for industrial applications
      M.L. LANGHORST, (The Dow Chemical Co., Analytical Sciences, 574 Building, Midland, MI 48667, USA)

      J. Planar Chromatogr. 2, 346-354 (1989). Review of the application of HPTLC in environmental, agricultural areas, toxicology, organic and polymer research, illustrating trace quantitative capabilities, high sample through puts, simple visualization, the ability to handle relatively „dirty“ sample matrices with minimal sample clean-up and the ability to help solve difficult analytical problems. Applications are monitoring airborne reactive chemicals, compound stability studies, agricultural formulation research, characterization of polymers and copolymers and screening of surfactants in latex by HPTLC.

      J. Liq. Chrom. & Rel. Technol. 26, 2751-2761 (2003). TLC of nonionic surfactants (Arkopal N40, 50, 60, 80, 90, 100, 130, 150, 230, 300, Sapogenate T60, 100, 110, 130, 138, 180, 300, 500) on zein-coated aluminium oxide prepared by dissolving 0.5 g zein in a mixture of 160 mL propanol and 40 mL water and adding to 20 g aluminium oxide, removal of the solvents at 70°C in vacuum and coating of plates with a suspension of 5 g of stationary phase and 14 mL water. Bidistilled water and water - methanol mixtures containing 5, 10, and 15 vol.% methanol were used as stationary phases. Developments were also carried out in aqueous solutions of 0.5, 1.0, 2.0, 3.5, 4.0, and 5.0 M LiCl, as well as e.g. aqueous solutions of 4 M NaCl, 4 M KCl, 4 M RbCl, 4M NH4Cl etc. After drying at 105°C, the surfactants were detected by exposure to iodine vapor.

      TLC-Spectrodensitometric determination of Polidocanol (Thesit®) in different pharmaceutical preparations
      R. BRAHM, W. ZIEGENBALG, B. RENGER*, (*Mundipharm GmbH, Postfach1350, D-6250 Limburg (Lahn), FRG)

      J. Planar Chromatogr. 3, 77-78 (1990). Quantitative TLC determination of Polidocanol (mixture of monolauryl ethers of polyethyleneglycols) on silica with dichloromethane - methanol 15:2 with traces of water as eluent. After drying immersion for 2 s in Dragendorff’s reagent. Quantification by densitometry (absorbance at 550 nm).

      Water as a detecting agent in thin layer chromatography of surfactants
      S. SIMUNIC, Z. SOLJIC, (Fac. of Chem. Engineering and Technol., Univ. of Zagreb, Marulicev trg 20, 10000 Zagreb, Croatia)

      J. Liq. Chrom. & Rel. Technol. 22, 1247-1256 (1999). HPTLC of surfactants (Jugopon, Texapon N 25, Rewoquat WE 20, W 75, Brij 35, Tenzilin AA 65) on silica gel with ethanol and ethanol - water mixtures with up to 20% of water as mobile phase. Detection by reaction with i.a. methylene blue and bromophenol blue and by dipping into water after development. Only anionic surfactants gave white spots with gas bubbles (rarely and slightly some nonionic surfactants, and never cationic). Therefore, this occurrence can be used for detection (and identification) of anionic surfactants, and for determination of polarity of surfactants.
