Certification of Standard Reference Material® 955d, Toxic Elements and Metabolites in Frozen Human Blood

Standard Reference Material (SRM) 955d is intended for use in validating analytical methods for measuring toxic elements and mercury species in human blood, and in value assigning locally produced control materials analyzed using the validated methods.A unit of SRM 955d consists of six vials of frozen human blood with two vials at each of three mass concentration levels.Each vial contains nominally 1.6 mL of whole blood.This publication documents the production, analytical measurements, and statistical evaluations leading to the certification of the SRM.
