A measuring device for X-ray fluorescence analysis, in which a specimen disposed on a carrier is stimulated by glancing incident radiation and examined spectrometrically by a detector which may be arranged above the specimen. On the upper side of an e.g., box-shaped housing in which a vacuum can be created, there is provided a detector extending into the interior of the housing. This detector is connected to the housing by means of a pivotable frame within the housing. The pivot axis of the frame is located in the measuring plane of the detector. Provided on the pivotable frame is a remote controllable specimen exchanger and a remote controllable disengaging device for shifting the specimen carrier out of its operative position, the disengaging device being substantially aligned with the detector axis. The pivotable frame has furthermore provided thereon counter bearings for the specimen carriers; these counter bearings surround the measuring region. In one side wall of the housing there is provided a ray inlet window which is aligned with the measuring plane. This window is for a radiation source which can be placed externally in front of the housing. |
