HMTC Studies have shown that some arsenicals are much more toxic than others. This article discusses a new analytical method, developed by Rockwell International's Environmental Monitoring and Services Center, which can be used to separate and identify five arsenic species: arsenite, arsenate, methanearsonate, cacodylate, and p-aminophenylarsonate. A schematic diagram of the automated Rockwell method is provided. Prior to the development of this method, the analytical procedure OSHA recommended could not distinguish between organic and inorganic arsenics. The automated Rockwell method converts arsenicals to arsine.
