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.
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.
This sample has been designed to be totally used. Do not subsample since intra-sample homogeniety cannot be assured.
Transfer the entire contents of the sample vial and rinse the vial with 2 small aliquots of extraction solvent adding rinseates to the extraction vessel. Complete the analysis according to your normal.
Report results in units of mg/kg based on a 10g sample size. No dry weight correction is needed.
Certified concentration is based upon the gravimetric/volumetric true value when prepared according to instructions.
Acceptance limits are based upon USEPA solid and chemical Interlaboratory studies.
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
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.
All balances are checked daily by an in-house standard operating procedure. The weights used for this daily verification are calibrated annually by an ISO 17025 accredited calibration laboratory and are certified traceable to NIST. Certificate of Calibration and Traceability available upon request.
Thermometer: All thermometers are NIST traceable through thermometers that are calibrated annually by an ISO 17025 accredited calibration laboratory.
Glassware: All glassware used in the manufacture of our standards is Class A. An in-house standard operating procedure is used to verify all glassware prior to it being placed into service. Volumetric pipetors are calibrated every four months by an ISO 17025 accredited calibration laboratory.
