Certified reference materials for arsenic species in biological materials

The main issues to be controlled during the analysis of biological materials for the speciation analysis of arsenic are:
  • quantitativeness of extraction of the arsenic species of interest from the tissue
  • preservation of the different arsenic 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:
NIESNIES-14Brown algae[inorganic arsenic]
Freeze-dried human urine           
Total arsenic, arsenobetaine, Dimethylarsinic acid, Se, Zn
SRM 2669
Frozen human urine
total arsenic, monomethylarsonic acid (MMA), dimethylarsinic acid (DMA),trimethylarsine oxide, arsenobetaine, arsenocholine
NISTSRM 3669Frozen human urinetotal arsenic, monomethylarsonic acid (MMA), dimethylarsinic acid (DMA), arsenobetaine
