A sample plate for mass spectrometric analysis of a specimen is provided comprising a substrate having an electrically conductive surface, a mask applied to the electrically conductive surface. The mask is applied to the substrate with a rough surface to form at least one sample site. The sample site comprises a central portion formed from the electrically conductive surface and a marginal portion formed from the mask where the marginal portion is more hydrophobic than the central portion.
L'invention concerne une plaque témoin pour l'analyse spectrométrique de masse d'un spécimen. Ladite plaque témoin comprend un substrat possédant une surface conductrice d'électricité et un masque appliqué sur ladite surface. Le masque est appliqué sur le substrat pourvu d'une surface rugueuse pour former au moins un site témoin. Ce site témoin comporte une portion centrale formée à partir de la surface conductrice d'électricité et une portion marginale formée à partir dudit masque, la portion marginale étant plus hydrophobe que la portion centrale.
