Advanced Mass Spectroscopy Techniques and Elemental Interference Analysis
This lecture explores advanced concepts in mass spectroscopy, focusing on ion sources, mass selectors, detectors, and data processing techniques. It delves into the intricacies of mass spectrometers (MS) and discusses applications such as Inductively Coupled Plasma (ICP) mass spectrometry. Key interactions and interferences between elements, including iron, nickel, cobalt, and cerium isotopes in aqueous solutions, are examined. The lecture aims to provide a comprehensive understanding of mass spectrometry technologies and their applications in elemental analysis.
