Advanced analytical techniques are adopted to replace toxic and harmful analytical methods, and hydride generation - non-dispersive atomic fluorescence spectrometry is used to replace catalytic oscillopolarography for the determination of arsenic, antimony, selenium, tellurium, etc. Seven new analytical methods were formulated and redrafted, including the inductively coupled plasma atomic emission spectrometry analysis method and the Méthode ya analyse ya mercure, etc.
