Abstract
The invention relates to a method and a device () for determining the amount of a target component () in a sample, wherein magnetic particles () can bind to a contact surface () with kinetics that depend on the sample-amount of the target component. The method comprises at least two washing steps during which magnetic particles () are magnetically moved away from the contact surface () and corresponding measurements of the remaining amount of magnetic particles () at the contact surface (). The amount of target component in the sample is estimated from at least one of such measurement results. The measurement allows to determine also high concentrations of target component for which the sensor surface () is saturated in a steady-state.
