摘要
介绍了新一代高灵敏度手提式X射线荧光仪 ,该仪器由电制冷Si PIN半导体X射线探测器、放射性同位素X射线激发源和基于PC/ 10 4工控机的 4 0 96道多道脉冲幅度分析器组成 ,对铜、锌、砷等元素的分析检出限为 10× 10 -6,适用于野外现场的天然岩石、土壤和水系沉积物的多元素含量的定量测定 ,基本满足新一轮地质大调查的需要 ,特别是二、三级异常点 (带 )的快速查证与野外追索工作。
This paper reports a highly sensitive X ray fluorescence analyzer for geological survey, which is composed of a Si pin X ray detector with thermo electrical cooler, isotope sources and a 4096 channel MCA based on PC/104 computer. Its analytical detection limits are about 10×10 -6 for Cu, Zn, As and other mineral elements. This analyzer can be used to conduct insitu determination of multi element concentrations in natural rock, soil and other mineral products.
