Abstract

SLEW-4 is an estuarine water Certified Reference Material (CRM) from the National Research Council Canada (NRC) with information on trace element content. A unit of SLEW-4 consists of approximately 200 mL of estuarine water. 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.
