Q:
What is trace element analysis ?





A:
  • Sample preparation is usually
    destructive, usually dissolution in acids, and
    include Atomic Absorption, Atomic Emission
    and Atomic Mass Spectrometry.





  • Various technologies are available, but
    must be careful of various types of interference
    that can lower accuracy and precision.


  • Flame AA Inductively Coupled Plasma Emission -
    radial and axial (ICP)
  • Graphite Furnace AA (GFAA)
  • ICP Mass Spectrometry (ICP-MS)
  • Must be careful of various types of interference
    that can lower accuracy and precision
