A method for quantitative analysis in situ of at least one of the elements in a Matrix, and a corresponding device.

摘要

Method and apparatus for Performing quantitative in situ Analysis of elements in an array.It includes the following Operations: Drilling a Borehole into the Matrix; Insert within the same Tube (20) containing a Spring (50) of particles or electromagnetic radiation has sufficient energy to produce x-ray fluorescence of the element or elements Analysis of (60) and a detector capable of detecting The Spectrum of the x-ray fluorescence; radiatingR The Matrix adjacent to the Spring with particles or electromagnetic radiation; detecting at least a portion of the Spectrum of x-ray fluorescence produced by such irradiation; and analyze the detected Spectrum, previously developed in the Electronic Circuit (70) and transmitted Or by cable (80) to an Analyzer located outside the Borehole,So that develop from this spectrum A quantitative estimate of the concentration of at least one of the elements present in the Matrix. Application Test of minerals in boreholes, Trials and in front of Mine Ground Surface Oceanographic and extraterrestrial Exploration, Analysis of material and in Medicine.
