Workplace air - Determination of particulate arsenic and arsenic compounds and arsenic trioxide vapour - Method by hydride generation and atomic absorption spectrometry
Gives a method by hydrid generation for the atomic absorption spectrometric determination of the mass concentration of particulate arsenic, arsenic compounds and arsenic trioxide vapour in workplace air. Applicable to the determination of mass concentrations of approximately 100 ng to 125 g of arsenic per sample. Not suitable for the determination of arsenic in the form of metal arsenides.
