Types of interferences - atomic fluorescence spectrometry, Chemistry

Types of interferences:

Within an atomic spectrometric method, interferences are produced through the non- analyte elements of the sample. The probable interferences that could influence the results of analysis through AFS are as follows.

  • The chemical interferences arising out of molecular species holding analyte that in turn decrease the percentage of gaseous analyte atoms or spectral because of radiation other than the atomic fluorescence.
  • The spectral interferences arise because of the overlapping of the matrix emissions along with the emission of the sample and result in the decrease in resolution of the spectrum. A spectral interference consists of the scattered light, molecular fluorescence, non analyte fluorescence, and the light emission through the atom cell.
  • Scattering is other area of concern and appropriate measures required to be taken up to minimise them.
