Abstract
The invention relates to device for the qualitative or quantitative measurement of magnetic particles, which device (10) includes a coil arrangement (20 - 23), arranged to form an inductance bridge (19), of which coils (20, 21) at least two are arranged to operate as a measuring part (17), on which the magnetic particles (12) to be measured are arrangeable to act simultaneously, and part of which coil arrangement (20 - 23) is arranged to operate as a reference/compensation part (18), and from the signal of which coil arrangement (20 - 23) a change of inductance correlating to the number of magnetic particles is arranged to be detected. The coils of the measuring part are arranged in an axial arrangement relative to each other.
