Semi-quantitative analysis in modern XRF instruments is a unique method which is performed without reference materials for the unknown samples. This report demonstrates determination of chemical composition in geological samples using semi-quantitative analysis by the pressed powder method on a WDXRF spectrometer.
The 2024 Emerging Leader in Atomic Spectroscopy Award
January 1st 2024This year’s Emerging Leader in Atomic Spectroscopy Award recipient is Eduardo Bolea-Fernández. For the past decade, Bolea-Fernández’s research has focused on the development of a newly introduced technique, termed tandem ICP-mass spectrometry (ICP-MS/MS), for ultra-trace elemental and isotopic analysis. Senior technical editor Jerome Workman discusses Bolea-Fernández’s work here.
Advancements in Non-Invasive Analysis of Historical Metal Artifacts
December 19th 2023Studying historical ancient artifacts requires the use of a nondestructive technique to analyze the metal surfaces of these objects. This study presents two approaches that improves on existing methods when conducting alloy analysis.
