This certified reference material (CRM) was manufactured and certified by NSI Lab Solutions according to quality procedures meeting our accreditation requirements of ISO 17034:2015 and ISO/IEC 17025:2017. Our certificates and scopes of accreditation may be viewed at www.anab.org. 

Packaging, Storage, Instructions For Use

This CRM is packaged in a sealed container and must be stored at 2°C to 8°C. To use this CRM, allow it to reach room temperature. Add 1mL of the spike solution to 1g of matrix. Complete the analysis according to your normal procedures. Results in units of mg/kg based on a 1 g sample size. No dry weight correction is needed. 

Certified concentration is based upon the gravimetric/volumetric true value when prepared according to instructions. Traceability Information

Analyte Source Materials: The highest purity analyte source materials are used in the manufacture of this standard. The actual purity is referenced above. 

Method: This CRM was verified Volumetrically/Gravimetrically and Analytically 

Balance: All analytical balances are calibrated on a semiannual basis by an ISO 17025 accredited calibration laboratory and are traceable to NIST. Traceable Calibration Certificate available upon request.
