Speciation Analysis of Arsenic by Hydride Generation-Cryotrapping-Atomic Fluorescence Spectrometry: Achieving Extremely Low Detection Limits with Inexpensive Instrumentation

Abstract

Extremely low detection limits of arsenic species can be also achieved with an inexpensive instrumentation like AFS. Speciation analysis of arsenic was done in this work by hydride generation coupled to cryotrapping and to a atomic fluorescence spectrometer.
