Nitrate anion standard solution

Description

• General description: SRM 3185 consists of five sealed borosilicate glass ampoules, each containing 10 mL of solution that has been prepared gravimetrically to contain a known mass fraction of nitrate. The nitrate is dissolved in filtered (0.22 μm) water, which has a minimum resistivity of 18μΩ cm.SRM 3185_certSRM 3185_SDS
• Application: Nitrate anion standard solution standard reference material (SRM) is intended for use as a primary calibration standard for the quantitative determination of nitrate using anion ion chromatography (IC).
• Features and Benefits: Available with a certified mass fraction value of nitrate anion standard solution. Certified values are measured by, 1.Gravimetric preparation using high-purity sodium nitrate.  2. Anion chromatography calibrated using independently prepared sodium nitrate and potassium nitrate primary standard solutions. Certified values are traceable to the International System of Units (SI) and SI-derived unit of mass fraction.  The NIST certificate is provided with storage, handling, and use instructions.
