Abstract
A plate for laser desorption ionization mass spectrometry comprising an electrically conductive substrate (1) covered with an array of spots of sintered nanoparticles (2) acting as a highly efficient sorbing phase, a very sensitive photo-reactive phase and an ionization device when covered by an organic matrix or by a hole conductor or electron donor instead of an organic matrix.
Claims25
A plate for matrix-assisted laser desorption ionization (MALDI) mass spectrometry comprising an electrically conductive substrate at least partially covered with sintered nanoparticles, deposited as an array of individual spots, for use as a sorbing phase for a sample, and for supporting ionization of sorbed samples molecules covered by or present in an overlayer or matrix, the overlayer or matrix comprising at least a light absorber and a charge carrier acid.
