Matrix Deposition for High-Resolution Imaging

5-dihydroxybenzoic acid as a matrix. The distribution image indicates that analyte ions segregate during solvent evaporation in different areas of the matrix crystals. 

high-resolution MALDI imaging of peptides or phosphohpids from tissue is mostly achieved by the pneumatically assisted spraying of a matrix onto
