Application
Ethanol-water solution is intended for use with calibrating instruments and techniques used for the determination of ethanol in blood.
Features and Benefits
- The certified values for ethanol are provided, that are metrological traceability to the International System of Units (SI) derived unit for mass fraction, expressed as a percentage and determined by gas chromatography with flame ionization detection (GC-FID) and Karl Fischer analysis.
- Expiration details and instructions for use, storage and handling are provided on the NIST certificate.
