| Abstract | SALT-1 is an artificial sea salt Certified Reference Material (CRM) from the National Research Council Canada (NRC) to be used as a proxy for seawater. A unit of SALT-1 consists of approximately 4.1 g of salt powder certified for phosphate, silicate and nitrate. The entire content of the SALT-1 unit should be transferred into a 100 mL plastic volumetric flask and reconstituted in nutrient free purified water. The SALT-1 reconstituted solution has typical properties of seawater and it can be used for calibration, method development, validation, and quality control for the analysis of nutrients in seawater, similar to the NRC MOOS-3. |
