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 https://www.sigma-aldrich.com to view certified values, including uncertainty, date of expiry, and detailed information about trace impurities.

Application

Silicon standard solution can be used as a calibration standard for the determination of silicon in plants using inductively coupled plasma optical emission spectrometry (ICP OES).

Analysis Note

1000 mg/L Si in H2O, prepared with high-purity (NH4)2SiF6 and water.

Ultrasensitive Determination of Silicate in Process and Boiler Water Using Rapid Photometric Tests

Efficiency of industrial plants and equipment constitutes one of the basic preconditions for sustainable economic operations. One avoidable problem is posed by the undesirable build-up of deposits, i.e., scale – in pipes, boilers, and turbines, whose principal cause is silicate. A rapid and sensitive test can ensure control over this threat.
