Rigaku EDXRF application note #1495 demonstrates the analysis of lead-zinc ore using the empirical calibration method. Elemental analysis is important in the examination of ores, from screening throughout the processing areas to final determination. The described method yields excellent results for screening and characterization of lead/zinc ore at the mine site or processing facilities for optimum product QA/QC.
LIBS Illuminates the Hidden Health Risks of Indoor Welding and Soldering
April 23rd 2025A new dual-spectroscopy approach reveals real-time pollution threats in indoor workspaces. Chinese researchers have pioneered the use of laser-induced breakdown spectroscopy (LIBS) and aerosol mass spectrometry to uncover and monitor harmful heavy metal and dust emissions from soldering and welding in real-time. These complementary tools offer a fast, accurate means to evaluate air quality threats in industrial and indoor environments—where people spend most of their time.
