摘要：

The gas-phase basicities of three common matrices used in matrix-assisted laser desorption/ionization (MALDI) have been investigated using laser desorption with Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry. In bracketing type experiments, laser-desorbed ions from 2,5-dihydroxy-benzoic acid, alpha-cyano-4-hydroxy-cinnamic acid and sinapic acid were tested for their ability to protonate test substances, This study was not limited to protonated matrix species but also included prominent fragments.
