摘要
Presented is a device for the preparation of samples for ionization by laser desorption, especially MALDI, that comprises a sample support assembly with a surface which has an array of sites for holding substances, and an outer contour surrounding the sample site array, and a flat cover which can be placed flush on or over the surrounding outer contour such that a shielded gas compartment is formed between the cover and the surface, said cover having an array of apertures arranged such that each aperture comes to rest over a corresponding sample site. A gas transport system is also provided on the assembly and cover, which serves to introduce a protective gas into the shielded gas compartment between cover and surface so that a protective gas atmosphere is generated in the gas compartment to protect the substances on the sample sites against atmospheric influences. An associated method is also described.
