Microwave induced plasmas with an Okamoto-cavity (Okamoto-cavity MIP) are noted as a new excitation source in atomic emission spectrometry. The Okamoto-cavity MIP can be sustained with various plasma gases, and can produce each stable plasma with a high robustness against loading of various types of samples. For example, the oxygen-containing MIP becomes an effective atomization and excitation source for direct injection of organic solvents analysis because they are completely burned in the plasma. In this review, the fundamental structure of the microwave cavity, the spectrochemical characteristics, and the analytical applications are summarized from reference papers.
