The Orbis Micro-XRF Analyzer Series

摘要

Building on more than 10 years of Micro-XRF experience, the Orbis spectrometer yields a system with excellent Micro-XRF capability while setting a new standard in analytical flexibility. The Orbis incorporates a unique motorized turret integrating video and X-ray optics allowing coaxial sample view and X-ray analysis. The turret can accommodate two additional collimators along with the X-ray optic for a total of three X-ray beam sizes to expand the Orbis analytical capabilities beyond traditional Micro-XRF analysis. Primary beam filters can be used with all spot sizes available on the turret to allow true XRF analytical capabilities in a micro-spot analysis. The working distance is increased to allow analysis over rougher sample topography without sacrificing signal intensity. The Orbis is a table-top unit with powerful, easy-to-use analysis software. Orbis users can make elemental analyses on small samples such as particles, fragments and inclusions, or automated multipoint and elemental imaging analysis on larger samples with all the benefits and simplicity of an XRF analyzer. Benefits include: (1) Nondestructive measurement; (2) Minimal sample preparation (for example, no sample coating is necessary); (3) Improved sensitivity for many elements in comparison to SEM/EDS; (4) Inclusion and coating thickness analysis with the penetrating power of X-rays; (5) Analysis of wet samples.
