Reducing Agents (for Hydride AAS)

The method of hydride atomic absorption spectrometry is used for the analysis (especially traces) of arsenic, antimony, tin, selenium, bismuth and mercury. It is used to separate and preconcentrate analytes from sample matrices by a reaction that turns them into their hydride vapors. Sodium borohydride is the common reagent of choice for the reduction. Fluka reagents are specifially analyzed to ensure the absence of hydride generating metals.
