Separation space for isotachophoresis with radiation detection

The facility allows to detect radiation in an arbitrary point without disturbing the process of separation and to detect the state and/or place of complete separation of components. It also allows the measurement of the moving zone boundary. The separation space consists of electrode areas with auxiliary equipment interconnected by means of a capillary on a support structure and of a radiation source and a detector. The support structure with electrode areas with auxiliaries is pivoted with regard to the detector and is fitted with a capillary arranged to a ring and a capillary pressure ring defining the slot for the radiation source rays passing through the capillary to the detector. The axis of rotation and the axis of the ring mounting are identical. (J.P.)
