Application

Ethanol-water solution standard reference material (SRM) is primarily intended for calibrating instruments and techniques used in determining ethanol concentrations in water-based media.

Features and Benefits

• Available with a certificate documenting NIST-certified mass fraction value of Ethanol.
• The certified value is obtained from the gravimetric preparation of the solution and from the analytical results determined using gas chromatography.
• The certified value is metrologically traceable to the SI unit of mass, expressed as a percent.
• The NIST certificate is provided with expiration certificate, storage, handling,use, and maintenance instructions.
