Abstract

NASS-7 is a seawater Certified Reference Material (CRM) prepared at the National Research Council of Canada (NRC) with information on trace element content. A unit of NASS-7 consists of approximately 200 mL of seawater. This material is intended for use in the method development, validation, and quality control for the analysis of trace and matrix constituents in seawater matrices.
