ABSTRACT:
A fluorescent X-ray analyzer having a source of X-rays and a detector for measuring fluorescent X-rays utilizes a sample cell having an inner and outer cell frame that captures an X-ray transmissive member. The inner cell frame has a lower surface co-planar with a sample measuring surface defined by the X-ray transmissive member. A sample cell stand assembly includes an outer cell frame member and an inner cell frame member with respective apertures. An X-ray transmissive member extends across the central apertures. The inner stand frame member contacts the inner cell frame member to provide a fixed distance relationship between the detector and the sample measuring surface.
