An ion microscope equipped with a resistive anode encoder imaging system has been used to acquire molecular secondary ion images, with lateral resolutions on the order of 1 μm, from several quaternary ammonium salts an amino acid, and a polynuclear aromatic hydrocarbon which were deposited onto copper transmition electron microscope grids. All images were generated by using the secondary ion signal of the parent molecular species
