Application
Calcium Carbonate standard reference material (SRM) is primarily intended for calibrating, validating, and standardizing analytical methods used in clinical analysis for determining calcium (Ca) and carbonate.

특징 및 장점

• The certified mass fraction values for elements are provided on a dry-mass basis and values are metrologically traceable to the SI unit of mass, expressed as a percentage.
• Provided with non-certified values ideal for method harmonization, method development, and process control.
• Expiry date, instructions for storage and usage are detailed on the NIST certificate.

분석 메모

Standard Reference Material (SRM) 915c Calcium Carbonate is certified as a chemical substance of known purity.
