Portable soil heavy metal analyser

Abstract

The invention relates to a portable soil heavy metal analysis instrument, which includes an X-ray tube, an X-ray exit window, a detector, a micro-processing computer, a GPS receiver and a power supply device, the micro-processing computer has a CF card slot, and the GPS receiving The X-ray tube is inserted into the CF card slot of the micro-processing computer. When measuring, the X-ray tube emits X-rays to detect the fluorescence generated by the sample excited by the X-rays. After processing, the micro-processing computer conducts energy spectrum analysis to obtain the specific content of The content and content of the sample, the built-in GPS system of the microprocessor computer can carry out the global positioning of the sampling position, and the position information and measurement data are generated at the same time. The invention avoids errors in manual recording and statistics, improves efficiency by several times compared with traditional measuring methods, does not produce substances harmful to the environment, and can perform heavy metal testing on large-area, fast and non-destructive field soil.

Description

technical field [0001] The invention relates to an instrument for analyzing metal components and contents in soil, in particular to a portable soil heavy metal analysis instrument with the function of sampling and positioning. Background technique [0002] X-ray fluorescence analysis is a technique for qualitative and quantitative analysis of multiple elements at the same time. It has the characteristics of rapid and non-destructive analysis of substances in different forms. In the analysis of soil composition and element content, using a portable X-ray fluorescence analyzer for on-site testing, collecting analysis results, and evaluating soil heavy metal pollution has very significant advantages. [0003] Due to the traditional X-ray fluorescence analyzer for the analysis of heavy metals in soil, such as the XR306-RoHS dedicated X-ray fluorescence spectrometer is composed of an instrument host and a commercial PC, and is powered by an external 220V mains power supply, which...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcoming that current laboratory X-ray fluorescence analyzers are not suitable for on-site testing, and solve the shortcoming that sampling point position data and measurement results cannot be integrated, Provide a portable soil heavy metal analysis instrument with sampling and positioning function. Using this instrument can not only realize the on-site non-destructive and rapid detection of soil heavy metal element content, but also perform global positioning system (GPS) geographical coordinate positioning on the sampling test site, and easily determine the composition of the sample. Data and location data are generated at one time, making the analysis of heavy metals in soil targeted, systematic and highly accurate
