教你如何选择AAS和ICP-OES仪器

Introduction
The analyst today is faced with a bewildering choice of techniques when deciding to enter the field of elemental analysis. Should it be Atomic Absorption Spectrometry (AAS), Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), Inductively Coupled Plasma Mass Spectrometry
(ICP-MS) or Inductively Coupled Plasma Arc Spark (ICP-AS)?
One of the areas where the choice is supposedly most difficult to resolve concerns AAS and ICP-OES. When ICP-OES was developed in the mid-1970’s, the scientific press read ‘ICP is going to sweep AAS away and take over as the only analytical technique worth considering for liquid samples’. Today, whilst there has been a significant move by analysts away from AAS towards ICP-OES, it is important to remember that in fact the techniques are complimentary rather than competitive.
