Workplace air. Determination of particulate arsenic and arsenic compounds and arsenic trioxide vapour. Method by hydride generation and atomic absorption spectrometry1 Scope This International Standard specifies a method for the determination of the mass concentration of particulate arsenic and arsenic compounds and arsenic trioxide vapour in workplace air, using either continuous flow hydride generation or flow injection analysis hydride generation and atomic absorption spectrometry. The method is not suitable for determination of arsenic in the form of metal arsenides which decompose in the presence of water or
