Other Notes

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
Used to check the standard curve, the procedure for interelement correction and other spectral interferences. These standards are carried through the entire analytical operation of the method. If the determined concentration is not within ±5.0% of 1 μg/mL, the laboratory performance is unacceptable. The source of the problem should be identified and corrected before continuing the analysis. For use in US EPA method 200.7 (Revision 4.4) and SW-846, method 6010 (Third Edition).
