Application

Fine carbon standard referencematerial (SRM) is intended to evaluate the chemical analysis methods and tocalibrate the instrumental methods of analysis.

Features and Benefits

• NIST certified values for mercury are provided, values are metrologically traceable to the SI unit of mass, expressed as milligrams per kilogram.
• A reference value for gold is reported based on dry mass basis and determined by inductively coupled plasma massspectrometry (ICP-MS).
• The information value for cyanide is provided and is determined using EPA method SW-846 9012a, and the mass fraction is reported on a dry mass basis.
• Expiration details and instructions for use are provided on the NIST certificate.
