摘要: Coupling of planar chromatography with mass spectrometry (thin-layer chromatography/high-performance thin-layer chromatography-mass (TLC/HPTLC-MS)) allows highly targeted recording spectra, only zones interest. Owed to the locally fixed, separated compound on adsorbent, antecedent evaluation is allowed. MS system contaminations through matrix, background, or negative samples are reduced a minimum. In addition interest, e.g. TLC-MS Interface liquid extraction surface analysis, whole track hR F -substance window can be scanned via matrix-assisted laser desorption ionisation ambient techniques like electrospray ionization and direct analysis in real time, all under precondition high spatial resolution satisfying detectability low nanogram per band range.
