Patent ID: 8129138

Claim:
A method for the determination of an analyte in a liquid sample with the aid of an analytical apparatus, the method comprising (a) applying a liquid sample to a test system comprising several successively arranged measuring areas, and through which liquid sample can flow; (b) measuring a first measuring signal s i and a second measuring signal s j wherein the first measuring signal s i indicates a part of the analyte bound in a ith measuring area and the second measuring signal s j indicates a part of the analyte bound in a jth measuring area that is arranged downstream the ith measuring area on the test system, (c) calculating a concentration measure N correlating with the concentration of the analyte in the liquid sample is determined by the analytical apparatus in accordance with the following linkage of measuring signals: N = ( s j ) i + 2 [ s i - ( ( s i ) j - i - 1 · s j ) 1 j - i ] · ( ( s i ) j - i - 1 · s j ) i j - 1 .
