Abstract:
1. A method for use in the detection of an analyte in a liquid sample, said detection taking place in a process on a substrate, said method comprising the steps of: adding liquid sample to a receiving zone on a surface of said substrate; transporting at least a subset of said liquid sample through capillary action from said receiving zone where said sample is added, to an optional zone where a reaction/detection takes place, said transport by capillary action defining a lateral flow path, said substrate being non-porous, at least part of said lateral flow path comprising areas of projections substantially vertical to said surface, and having a height (H), diameter (D) and reciprocal spacing (t separating unwanted components in said sample without interruption of said capillary flow wherein said separation step is achieved using means for separation comprising a filter that retains said unwanted components and wherein a device retaining said substrate is constructed to induce capillary action without the need for a cover.
