Certified reference materials for arsenic in marine animal tissues




The main issues to be controlled during the analysis of biological tissues for the speciation analysis of arsenic are:
  • quantitativeness of extraction of the species of interest from the tissue
  • preservation of the different species during the analysis
  • mass balance with respect to arsenic species determined

CRMs play a major role in the development and validation of methods and for quality control. The following certified reference materials (CRMs) are available for speciation analysis:
