Abstract: A rejector device for use within a system for sorting discrete objects, the divert device comprising at least one divert device arranged to change the trajectory of an object; and drive means arranged to drive the divert device between at least three discrete positions such that in use, at least one of said discrete objects passes along one of three paths.

Abstract: The present invention provides a method for capacitive detection of the presence of target sample on a substrate, which comprises the steps of: binding a target sample to selective binding sites on the substrate, the target sample being directly or indirectly labeled with conductive labels, and sensing the presence of the bound conductive labels to a binding site to thereby determine the presence of the target sample. The sensing step is carried out by a capacitive detection of the presence of the conductive labels. The present invention also provides a capacitive sensor device for determining the presence of a target sample. Conductive labels are directly or indirectly couplable to the target sample.
