摘要
Acquisition of tandem mass spectra from peptides or other analytes deposited on non-conductive membranes is inhibited on instruments combining matrix-assisted laser desorption/ionization with tandem time-of-flight analyzers (MALDI-TOF/TOF(TM)) due to a charging effect. A thin layer of gold renders the membrane conductive. This allows adequate data acquisition on MALDI-TOF/TOF(TM) systems. Therefore, this methodology extends the capacity of the molecular scanner concept to tandem mass spectrometry. Copyright (C) 2005 John Wiley Sons, Ltd.
