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

Silicon standard may be used as calibration standard during determination of silicon from powdered aluminium oxide and petrochemical products using graphite-furnace atomic-absorption spectrometry (GF-AAS).

Analysis Note

1 g/L Si in 2% sodium hydroxide, prepared with high purity silicon metal, NaOH and water
