An arrangement for a MALDI sample plate for ion mass spectroscopy is disclosed. The sample is configured to shape the hypersonic explosion which creates the ions generated in a MALDI-type time-of-flight mass spectrometer. The MALDI sample plate includes a glass wafer formed from a plurality of clad glass fibers and has a first planar surface. The plate also has a plurality of micro-wells formed in the glass wafer. The micro-wells extend to a depth that is less than the thickness of the glass wafer and act to hold a spot sample in a manner that prevents spreading, maximizes the formation of ions, and shapes the resulting ion cloud to improve ion migration.
