ABSTRACT:
Ion source assemblies for generating ions for laser desorption mass spectrometry. An ion source assembly includes a target for receiving analyte samples and a plurality of rods. The rods define an interior volume having an axis extending away from a surface of the target for transporting ions. One or more of the rods include an aperture defining an opening through a cross-section of the rod. The aperture is configured such that a laser beam can pass through the aperture to irradiate a location on the target surface to generate ions from an analyte sample deposited at the location.
