Abstract

This paper describes the use, for atomic absorption, of long, heated absorption tubes first described by Fuwa and Vallee. Heating the absorption tube provides advantages in increased sensitivity for certain elements and reduced interferences. The remaining effects of interferences are discussed, and methods for their control are given.
