Abstract
A sample plate structure is provided including a retainer plate having a central recess with a trough along its periphery, a sample insert plate which fits into and rests on contact surface of the recess, and a magnet that is held below the contact surface. A portion of the bottom surface of the insert is formed of a magnetic material. The magnet provides sufficient force to retain the insert plate in the retainer plate during MALDI MS analysis. The sample insert plate is provided with a peripheral configuration, which assures that the sample insert plate is properly oriented within the sample plate support structure and is held flat. A hole for a protrusion allows easy insert installation and alignment against the orientation feature in the recess as well as easy removal of the insert simply by pushing up from underneath the retainer plate. While the insert sample plate can be a consumable, the remaining portion of the apparatus can be reused.
