Abstract

An analytical device determines the analytes in a liquid sample. This device includes a layer of flat material which has a sample application area and a detection area thereupon. The detection area includes a reagent for determining the analyte, and the absorbent sample application area and the absorbent detection area are disposed within a liquid impermeable boundary. The layer of flat material also includes an absorbent connector which is disposed such that the sample application area and the detection area are connected by the absorbent connector. The liquid impermeable boundary and the absorbent connector prevents liquid from being transported between the sample application area and the detection area, except through the absorbent connector.
