Portable X-ray fluorescence spectrometer with an electric battery

Abstract

A potable X-ray fluorescence spectrometer composed of an electric battery X-ray generator and a silicon drift detector was made. Several kinds of samples, including toxic elements, such as lead and cadmium, were measured in air using this spectrometer. A possibility to analyze these toxic elements is discussed. It has been demonstrated that sufficient intensity for lead and cadmium was obtainable within 100 seconds to identify these elements.
