||This method updates and replaces MDHS 41 (see CIS 85-1616). Principle: particulate arsenic and arsenic compounds are collected on a membrane filter with a sodium carbonate-impregnated back-up paper pad. Arsenic trioxide vapour is collected by reaction with the sodium carbonate on the pad. The filter, pad and sample are digested in acid and the solution is prepared for hydride generation in a continuous flow or flow injection analysis hydride generation system. Gaseous arsine and hydrogen are separated and analyzed by atomic absorption spectrometry. Scope: suitable for sampling over periods from 15 minutes to eight hours; not suitable for the determination of certain metal arsenides or in the presence of transition metals.
