A Review of Tungsten Coil Electrothermal Vaporization as a Sample Introduction Technique in Atomic Spectrometry

Abstract

Tungsten coil electrothermal vaporization has served as an alternative sample introduction method in atomic spectroscopy for some time and is easily employed in a laboratory because of its mass production, ease of use, and small requirement for power. This review will focus on the use of the tungsten coil as an electrothermal vaporization sample introduction source in atomic absorption, emission, and fluorescence spectrometry over the past decade. Analyzed samples have both biological and industrial significance, illustrating the versatility of the technique. Since its conception 40 years ago, tungsten coil electrothermal vaporization continues to provide users with innovative options for spectroscopic analysis.
