Abstract
A mass spectrometry substrate includes an electrically conductive material providing an electrical conductivity that allows at least one of a first and a second surface of the substrate to be maintained at a desirable potential for ion extraction while ions are desorbed during ionization. A solid lattice material comprises a plurality of pores positioned in a plurality of layers that form a network of at least one continuous channel extending from a first surface of the substrate to a second surface of the substrate. Each of the plurality of pores are dimensioned and positioned in the plurality of layers so that a first group of substances are adsorbed or absorbed on the first surface and a second group of substances are adsorbed or absorbed on the second surface.
