Product Description
A sample is converted to arsenic gas. As the gas is generated, hydrogen sulfide is removed. This is done by surface contact or glass beads. The absorber tube absorbs the arsine gas and forms a red complex. It is then transferred to a convert and is read on a clorimeter or spectrometer. Glass beads may be used in the absorber tube for improved mixing generated gas. Glass beads are not part of the complete unit.
