The rapid determination of arsenic by optical emission spectroscopy using a microwave induced plasma source and a miniature hydride generation device

A simple technique for the determination of trace concentrations of arsenic is described; a miniature hydride generation device is employed for sample introduction of the gaseous hydride directly to a microwave induced helium plasma operating at atmospheric pressure and detection is effected by optical emission spectroscopy. A rapid, inexpensive and precise analytical method has been developed for the determination of arsenic. © 1984.
