|Abstract:||Microwave-induced plasma optical emission spectrometry (MIP OES) has increasingly become a major resource for multi-elemental analysis. One of the greatest breakthroughs in the field has been the development of a commercial instrument based on a Hammer cavity, which runs on N-2 gas obtained from an air compressor and a N-2 generator. Here, we describe the most recent advances in MIP OES instrumentation, as well as related developments in sample preparation and alternative sample introduction systems, strategies to reduce the effects of background emission and analytical signal fluctuations on accuracy, and new calibration and plasma diagnostics methods. Recently published studies have contributed to minimize matrix effects and improve robustness of MIP OES analysis, which allowed for applications involving a broad range of analytes and sample types. Together, the array of recent developments in MIP OES contributes to its acceptance and increasing adoption as a cost-effective alternative in trace element analysis|
