Efficiency Improvement in Flame Atomic Absorption Spectrophotometry

Abstract

The first efficiency improvement in flame atomic absorption spectrophotometry was based on development of free atom trapping devices. After that, thermospray system, the high efficiency sample introduction technique, was applied to use instead of nebulizer in atomic absorption spectrophotometer. Thereafter, tungsten coil was employed as an atomizer. Recently, continuum source was applied in flame atomic absorption spectrophotometer. A key benefit of this approach is the ability to analyze multiple elements simultaneously.
