Hydride generation:

Hydride generation methods are generally used for the determination of the elements which form hydride, for instance, arsenic, antimony, selenium and tellurium. In this method the analyte sample is treated along with sodium borohydride and hydrochloric acid to produce a volatile hydride of the analyte. This is then carried to the atom cell along with the help of an inert gas. The hydride generation methods provide better sensitivity for these components as compared to other flame atomic spectrometric techniques.
