Abstract
In geological survey and mineral exploration, ana1yzing geological samples plays an indispensable imprtant role. Along with the development of science, the methods of X- ray fluorescence analysis using XRF handheld device have been developed and put into application, marking a new step in geology in general and in Vietnam in particular. Comparing the analysis results of bed sludge samples using conventional ICP method and the ore samples using X-ray fluorescence analysis on XRF handheld device has initially idcntified the elements available in soil samples; the content range of the ỉdentỉfied elements is between 10 ppm and 10%; analysis error is ± 20%. The results showed that XRF handheld device is compatible for use in analyzing geochemical samples, sediments, bed sludge al Ihe field office.
