This Reference Material (RM) is intended for use in developing and validating methods for measuring relative differences in mercury (Hg) isotope-number ratios, R(XXXHg/198Hg). A unit of NIST-RM-8610 consists of four ampoules each containing approximately 5 mL of solution comprised of approximately 3% mass fraction nitric acid and 2% mass fraction hydrochloric acid, equivalent to amount-of-substance concentration (molarity) values of approximately 0.5 mol/L nitric acid and 0.5 mol/L hydrochloric acid. /// Sample value(s) - please ask for current certificate.
