Introduction

Energy dispersive X-ray fluorescence spectrometer is based on a sample of elements of higher energy beam or particle flow characteristics of X-ray excitation energy use Characterized by direct measurement of the amount of detector element excitation energy and the X-ray intensity, qualitative and quantitative analysis instrument. It is mainly used for smelting Gold, geology, minerals, petroleum, chemical, biological, medical, commodity inspection, criminal investigation, archaeological and other industries and fields. Energy Dispersive X-ray Fluorescence Spectrometer basic structure is as follows. --- High-voltage generator (high voltage power supply); --- X-ray tube or a source of excitation; --- Energy X-ray detector; --- Pulse amplifier; --- Multi-channel pulse analyzer, data processing and output devices. This standard aims to. --- Specification energy dispersive X-ray fluorescence spectrometer main performance test methods, progress and development of the industry; --- Provide technical support for products and product transactions entered into contracts to protect the interests of the supplier and the consumer; --- Useful for measuring the results and their presentation of unity, comparable. Energy dispersive X-ray fluorescence Spectrometer main performance test methods
