Abstract: The working principle of analysis technology of hydride generation-inductively coupled plasma atomic emission spectrometry, the reaction modes of hydride generation (acid mode and alkaline mode), hydride generation units (intermittent hydride generation units, continuous hydride generation units and self-made modification units) and the application of the technology in environmental analysis, food and drug analysis, geological analysis and other analysis, as well as the interference and elimination in hydride generation injection technology were reviewed. Meanwhile, the research progress of the technology in simultaneous determination of hydrogenated and non hydrogenated elements was briefly described, and the future development of the technology was prospected (91 ref. cited).
