Measurement and Results - NIST SRMs used for mercury (Hg) assays
Regarding your mercury standards, which NIST reference material(s) do you use to verify their concentrations? We want to find a suitable reference material, and want to use the same one used by the standard vendor.

We use two NIST Standard Reference Materials (SRM) to certify the mercury concentration in our products; one is used for direct-comparison ICP methods (SRM 3133), and the second is used as part of an EDTA Hg titration (SRM 928). |
