Device and method for performing X-ray analysis

摘要

The invention relates to a device for performing X-ray analysis. Device 1 comprises an X-ray tube 2 and at least one capillary lens 4 for focusing the X-rays in a micro-region at a location 5 for a sample for analysis. Device 1 further comprises a detector 6 for detecting X-ray fluorescence from the sample. Device 1 further comprises at least one energy-dependent filter 3 placed between the X-ray tube 2 and the capillary lens 4 . The filter 3 is adapted to substantially block X-rays with an energy which is lower than a predetermined threshold value.
