      Automated interface for hyphenation of planar chromatography with mass spectrometry
      H. LUFTMANN, M. ARANDA, Gertrud MORLOCK* (*Institute of Food Chemistry, University of Hohenheim, Stuttgart, Germany, gmorlock@uni-hohenheim.de)

      Rapid. Commun. Mass. Spectrom. 21, 3772-3776 (2007). A new fully automated online interface to couple HPTLC with ESI-MS/MS is presented for the first time. Among the major features of this interface are the time required for analysis, precision, suited for normal and reversed-phase layers and all plate sizes and carriers, no post-chromatographic process is required, it can be coupled universally with all LC-MS ion sources without any adjustment or mass spectrometer modification, and the quantitative analysis can be performed without any internal standard with a given detectability at the low-nanogram and even picogram level. The validation results for caffeine quantification in energy drinks and pharmaceutical samples, without internal standard, proved the reliability of the interface and its usefulness for quantitative analysis with comparable results to those obtained by validated HPTLC-UV methods.

      Comparison of two different plunger geometries for HPTLC-MS coupling via an extractor-based interface
      Gertrud MORLOCK*, Ute JAUTZ (*University of Hohenheim, Institute of Food Chemistry, Garbenstrasse 28, 70599 Stuttgart, Germany; gmorlock@uni-hohenheim.de)

      J. Planar Chromatogr. 21, 367-371 (2008). HPTLC of harmane (1-methyl-9H-pyrido[3,4-b]indole) and Glu-P-1 (2-amino-6-methyldipyrido[1,2-a:3’,2’-d]imidazole) on silica gel (prewashed with methanol) in a flat-bottom chamber with diethyl ether - methanol 49:1 at a relative humidity of 42 % and a temperature of 26 °C. Before development, the activity and pH of the silica gel were adjusted in a saturated twin trough chamber with 20 % aqueous ammonia (25 %) for 15 min. Quantitative determination by fluorescence measurement at UV 366/>400 nm. HPTLC-MS coupling via an extractor-based interface using a circular and an oval plunger for extraction of the adjacent heterocyclic amines. The circular plunger was easier to position, however the oval plunger was shown to be optimal (more selective) for adjacent bands.

The plate was overlaid with Shiga toxin (Stx), and the microbes were detected with primary anti-Stx and appropriate alkaline phosphatase labeled secondary antibodies. Bound antibodies were visualized by color development using 0.05 % 5-bromo-4-chloro-3-indolyl phosphate p-toluidine salt in glycine buffer. The GSLs were extracted from the plate and analyzed by electrospray ionization mass spectrometry (ESI-MS). Using the combination of a TLC overlay assay and nanoESI-QTOF-MS, the structural characterization of the functional Stx1 receptors of Raji and THP-1 cells is reported.
