AA Standards
AA Standards from Agilent
Agilent aqueous single element standards for AA are certified by high performance ICP-OES (HP-ICP-OES), a technique developed by the National Institute of Standards and Technology (NIST). NIST uses HP-ICP-OES to certify their SRM 3100 series of spectrometric single element solution standards. NIST recommends that all standards manufacturers use this technique to certify single element standards with high accuracy, low uncertainty, and direct traceability of both the certified concentration and the uncertainty to the NIST SRM 3100 series.
