An apparatus () for the measurement of a concentration of a charged species in a sample () is disclosed. The sample () comprises a plurality of types of charged species and at least one insoluble component. The apparatus () comprises a first circuit with a voltage control device () connectable to two first electrodes (') arranged along a channel () holding the sample () and a second circuit with a conductivity detection device () connectable to two second electrodes (&#x2032;) arranged in the channel (). The first circuit and the second circuit are dc and ac electrically isolated from each other.

Apparatus for the measurement of a concentration of a charged species in a sample

The invention provides a method for the measurement of a concentration of a charged species in a sample, the sample having a plurality of types of charged species and at least one insoluble component. The method comprises: providing the sample on a surface of a partly permeable layer; allowing components of the sample to pass through the partly permeable layer into a channel; and separating the components into sections, such that each at least one of the sections substantially comprises a single type of the plurality of the types of charged species, and determining the charge concentration in the at least one of the sections.
