Minerals in Drinking Water with the PinAAcle 500 AA Spectrometer

In this final part of our conversation with Harrington and Seibert, they discuss the main challenges that they encountered in their study and how we can improve elemental impurity analysis in pharmaceutical quality control.

In Part II of our conversation with James Harrington of RTI International in Research Triangle Park, North Carolina, who was the lead author of this study, as well as coauthor Donna Seibert of Kalamazoo, Michigan, they talk about the reproducibility for Hg and V, as well as the ICP-MS and XRF results compare to one another.

Spectroscopy sat down with James Harrington of Research Triangle Institute (RTI International) in Research Triangle Park, North Carolina, who was the lead author of this study, as well as coauthor Donna Seibert of Kalamazoo, Michigan. In Part I of our conversation with Harrington and Seibert, they discuss the impact of ICH Q3D and United States Pharmacopeia (USP) <232>/<233> guidelines on elemental impurity analysis and how they designed their study.

A 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.

A recent study conducted by researchers from the Korea Institute of Fusion Energy and Jeonbuk National University presented a novel technique for analyzing lithium isotopes in liquid samples.

A new study in Icarus by Fabian Seel and colleagues at the German Aerospace Center (DLR) reveals how atmospheric conditions significantly impact LIBS plasma behavior.
