Portable microbeam X-ray fluorescence spectrophotometer

Abstract

The invention discloses a portable microbeam X-ray fluorescence spectrophotometer, comprising a main frame, wherein an X-ray light tube and an X-ray detector are arranged on the main frame; a detected sample is arranged within a detection beam range of the X-ray light tube; the X-ray detector is arranged right above the detected sample; the fluorescence spectrophotometer also comprises an X-ray combined refractor which is used for selectively collecting an X-ray fluorescent light generated by a detected sample micro-cell; the X-ray combined refractor is connected with the lower end of the X-ray detector; the X-ray detector is arranged inside an image space of the X-ray combined refractor; the detected sample is arranged inside an object space of the X-ray combined refractor; the upper end of the X-ray detector is connected with a port for connecting an information collection system; a laser device is also arranged on the main frame; the detected sample is arranged within an irradiation range of the laser device. By adopting the portable microbeam X-ray fluorescence spectrophotometer, the structure is simplified and the size is reduced while the microcell resolution ratio is smaller than 10 microns; the portable microbeam X-ray fluorescence spectrophotometer is convenient to carry.

Description

technical field [0001] The invention relates to the field of X-ray detection and imaging, in particular to a micro-beam X-ray fluorescence spectrometer. Background technique [0002] X-ray fluorescence spectrometer (XRF, X-Ray Fluorescence) can perform simple, fast, high-resolution and non-destructive quantitative measurement and analysis of elements in various forms (solid / liquid / powder, etc.) samples under normal pressure. In recent years, many industries have put forward higher requirements for XRF's micro-area analysis capabilities, detection sensitivity and on-site analysis capabilities (for example, the micro-area resolution is required to be less than 10 microns), so light weight, portable, high-resolution, High-sensitivity micro-beam X-ray fluorescence spectrometer (micro-XRF) has become a current research hotspot. [0003] At present, the existing X-ray fluorescence spectrometers are generally not equipped with X-ray focusing devices, and the micro-area resolution ...
