Abstract

There is disclosed an analysis device for the analysis of a liquid sample, said device comprising a substrate, said substrate at least partly having projections substantially vertical to the surface of said substrate, and having a height (H1), diameter (D1) and center-to-center distance (x1, y1) such, that lateral capillary flow of said liquid sample is achieved, wherein that said substrate comprises at least one substrate zone comprising projections substantially vertical to the surface of said substrate, and having a height (H2), diameter (D2) and center-to-center distance (x2, y2), such, that lateral capillary flow of said liquid sample is achieved and wherein at least one substance is applied at least partly between the projections in said at least one substrate zone. Moreover there is provided a method for the analysis of a sample. The device and method provide for instance improved control of the dissolution of a substance.
