J. Planar Chromatogr. 11, 30-33 (1998). Investigation of the interaction of acids and bases with the components of HPTLC layers which lead to greatly altered HPTLC-FTIR spectra in direct HPTLC-FTIR on-line coupling. The cause is an acid-base reaction between the substance and the binder used in the precoated layer. For HPTLC-FTIR analysis of substances with acidic properties water-resistant silica gel 60 WRF 254s HPTLC plates should be used; it is preferable to use standard silica gel 60 F254 HPTLC layers for the analysis of basic substances. When acidic mobile-phase components (e.g. formic acid or acetic acid) are employed the use of water-resistant plates is advisable if HPTLC-FTIR coupling is to be employed for detection. Conversely it is advisable to use standard layers when basis mobile phase components are employed.

Use of silver gel as the surface enhanced subtract placed on the separated spots for measurement of FT-SERS. Investigation of the minimum detection amount for the compound, and the difference between the SERS and solid spectra.

Anal. Chem. 77, 1207-1215 (2005). The use of desorption electrospray ionization for coupling TLC with MS was demonstrated for prewashed wettable unpolar C18, C8, and C2 and for polar silica gel phases. The experimental setup and its optimization are described as plate positioning was a crucial factor of influence on the MS signal. TLC of rhodamine dyes on RP-8 and RP-2 phases with methanol – water containing 200 mM ammonium acetate 4:1, MS analysis in the positive ion mode via SRM. TLC of FD&C dyes on wettable RP-18 phases with water – acetone 7:3 containing 500 mM ammonium acetate, MS analysis in the negative ion full scan mode. TLC of a mixture of aspirin, acetaminophen, and caffeine from a medicinal formulation on silica gel with ethyl acetate – acetic acid 99:1, MS analysis in the positive ion full scan mode. The capability of detection was in the µg-range on silica gel phases and not as good as on unpolar phases.
