Chemex AAS (As; hydride evolution) (details not specified explicitly)



Chemex, atomic absorption spectroscopy - hydride evolution (arsenic)(details not specified explicitly)

General Methodology:

The element was determined by atomic absorption using a hydride evolution method wherein the hydride (AsH3 or SbH3) is evolved and passed through a heated quartz tube in the light path of an atomic absorption spectrophotometer.  The method is described by Aslin (1976).

Details of sample are not specified explicitly in open file.
