Schematic representation of workflow of MAIV methods. (A) The solution of 0.5 μL 3-NBN/clozapine:clozapine-d8 mixture was spotted on tissue surface and loaded into the vacuum of an intermediate pressure MALDI source. (B) Four 1 μL 3-NBN/clozapine:clozapine-d8 solution spotted on the tissue surface covering half of the tissue section, and exposed to vacuum of a modified skimmer cone of the overridden ESI source.
