This article is about the comparison between ICP-ES and AAS, including instrument principle and application, advantages and disadvantages of ICP-ES and AAS.
This document discusses the main differences between Atomic Absorption Spectrometry (AAS) and Inductively Coupled Plasma Emission Spectrometry (ICP-ES). It highlights that while AAS is a well-established technique relying on atomic absorption, ICP-ES uses an atomic/ionic emission spectroscopic technique involving a plasma generated at temperatures up to 10,000 K. The text explains how these fundamental differences affect detection capabilities for various elements and non-metals.
The basic difference is that one relies upon an atomic absorption process while the other is an atomic/ionic emission spectroscopic technique.
An ICP-ES instrument or graphite furnace AA can be left to run overnight as no combustible gases are involved.
The optical thinness of the ICP results in a large linear dynamic range of about 10^6.
