Sample support plates for mass spectrometry with ionization by matrix-assisted laser desorption
First Claim
1. Sample support for the mass spectrometric analysis of samples with ionization by matrix-assisted laser desorption, consisting of a flat sample plate to take the samples and a base structure, together creating the external form of a microtitre plate wherein the sample plate has holes or grooves, and the base structure is rigidly bonded to the sample plate by pins or protrusions anchored into the holes or grooves.

Abstract
The invention concerns the structure of the sample support plates for mass spectrometric analysis of organic samples ionized by matrix-assisted laser desorption. The invention consists of a highly flat plate, electrically conductive at least on its surface, rigidly bonded to a base structure in such a way that together they form a body having the external dimensions of a microtitre plate, but such that thermal distortions of the surface cannot occur. The base structure may have both depressions for frictional gripping by a robot as well as a machine-readable identifier.
