Abstract

Abstract The preparation of standard solutions containing mercury at the p.p.b. level has been investigated. Addition of sodium chloride to dilute mercury solutions below pH 1 improves the stability of the solutions greatly. Standard solutions containing 1–1000 p.p.b. Hg sealed in Pyrex glass ampoules are stable and usable for 18 months.
