【Abstract】 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 insitu determination of multi element concentrations in natural rock, soil and other mineral products.更多还原
