      On-Line Overpressure Thin-Layer Chromatographic Separation and Electrospray Mass Spectrometric Detection of Glycolipids
      W. CHAI*, Christine LETEUX, A. LAWSON, M. STOLL (*MRC Glycosciences Laboratory, Imperial College School of Medicine, Northwick Park Hospital, Watford Road, Harrow, Middlesex HA1 3UJ, U.K.,

      Anal. Chem. 75, 118-125 (2003). Online TLC separation and electrospray mass spectrometry (TLC/ESI-MS) by direct linking of a commercial overpressure TLC instrument, OPLC 50, and a Q-TOF mass spectrometer. Separation on silica gel with dichlormethane - methanol - water 60:35:8. A sensitivity of 5 pmol of glycosphingolipid was readily demonstrated for TLC/ESI-MS and 20 pmol for TLC/ESI-MS/MS production scanning to derive the saccharide sequence and long chain base/fatty acid composition of the ceramide. Initial preconditioning of TLC plates is necessary to achieve high sensitivity detection by reducing chemical background noise. Plates can be used repeatedly (at least 10 times) for analysis, although this may result in a minor reduction in TLC resolution. Following solvent development, separated components on the TLC plates can be detected in the conventional way by nondestructive staining or UV absorption or fluorescence and can be stored for on-line TLC/ESI-MS analysis at a later stage without reduction in mass spectrometric detection sensitivity and chromatographic resolution. Aspects for further improvement of OPLC instrumentation include use of narrower TLC plate dimensions and refined design of the eluate exit system.

      Analysis of Gangliosides Directly from Thin-Layer Chromatography Plates by Infrared Matrix-Assisted Laser Desorption/Ionization Orthogonal Time-of-Flight Mass Spectrometry with a Glycerol Matrix
      K. DREISEWERD*, J. MUTHING, A. ROHLFING, Iris MEISEN, Zeljka VUKELIC, Jasna PETER-KATALINIC, F. HILLENKAMP, S. BERKENKAMP (*Institute of Medical Physics and Biophysics, Westfälische Wilhelms-Universität Münster, 48149 Münster, Germany,

      Anal. Chem. 77, 4098-4107 (2005). Novel method for direct coupling of HPTLC with matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) for the analysis of biomolecules. HPTLC of gangliosides on silica gel with chloroform - methanol - water 24:17:4 containing 2 mM calcium chloride, with chamber saturation for 20 min. Detection by dipping for 10 s in 0.3 % (w/v) orcinol in 3 M sulfuric acid, followed by heating at 110 °C. Use of a glycerol as matrix, which provides a homogeneous wetting of the silica gel and a simple and fast preparation protocol. Use of an Er:YAG infrared laser, which ablates layers of 10 µm thickness of analyte-loaded silica gel and provides a soft desorption/ionization of even very labile analyte molecules. The orthogonal time-of-flight mass spectrometer employed in this study, finally provides a high accuracy of the mass determination, which is independent of any irregularity of the silica gel surface. The method is demonstrated by the compositional mapping of a native GM3 (II3-r- Neu5Ac-LacCer) ganglioside mixture from cultured Chinese hamster ovary cells. The analysis is characterized by a high relative sensitivity, allowing the simultaneous detection of various major and minor GM3 species directly from analyte bands. The lateral resolution of the direct HPTLC-MALDI-MS analysis is defined by the laser focus diameter of currently 200 µm. This allows one to determine mobility profiles of individual species with a higher resolution than by reading off the chromatogram by optical absorption.
