Analysis of Trace Elements and Fluorine in Pressed Pellets of Geological Materials

Multi-elemental analysis of samples from geological and allied materials represents a critical task for spectrometric instruments.

Users in science, industry, and business routinely use such spectrometric analysis on materials of widely varying composition. Energy-dispersive X-ray fluorescence (ED-XRF) instruments are often preferred for this work. ED-XRF methodology is an accepted technique for geochemical exploration and environmental monitoring. So these instruments’ stability and ease of use let them excel at critical tasks from rapid screening analysis to precise elemental determination. They provide fast, precise, accurate, and economical solutions for analysis of major, minor, and trace elements in these and similar applications.

Until recently the analysis of elements with low atomic number (like fluorine) was limited to specific calibrations for limited matrices.

This paper covers the use of an instrument equipped with a low-energy-window detector to analyze a wide range of elements (including fluorine) in samples of geological and allied materials, prepared as pressed powder pellets. Using polarization, band-pass filter, and direct excitation technologies, it proved a powerful analytical tool to satisfy the needs of high precision and low detection limits.
