Abstract
The invention is directed to an apparatus for determining the component of paramagnetic substances such as oxygen. This determination is made with a magnetic field source and an even number arrangement of magnetic field cores, with each field core being surrounded by a measuring field coil for detecting the magnetic changing field generated by a rotatable cuvette. The apparatus is improved in that the formation of the magnetic stray fields is reduced and the component of the magnetic flux which is effective for measurement and which passes through the cuvette is increased. For this purpose, the cuvette is mounted in the housing of the apparatus in such a manner that its rotational plane partitions the housing into two component regions. The magnetic field source is arranged in one component region and the magnetic field cores and the measuring field coils corresponding thereto are arranged in the other component region of the housing.
