General description

This certified reference material (CRM) is produced in accordance with ISO 17034 and characterized in accordance with ISO/IEC 17025. This CRM is traceable to SI unit kg and measured against primary material from a National Metrology Institute (NMI), e.g. NIST.

Please visit ISO certificates and Site Quality Self-Assessments to access the current certificates of accreditation.

Download your certificate at http://www.sigma-aldrich.com to view certified values, including uncertainty and expiry date.

Application

Potassium standard has been used as a calibration standard to determine the concentration of potassium present in minced beef using atomic absorption spectrophotometry(AAS).

Analysis Note

1 g/L K in 2% nitric acid, prepared with high purity KNO3, HNO3 and water
