Short
Explanation in regards to: Elemental Hg, Oxidized Hg, and the Weekly Integrity Test
•The
Thermo 81i Mercury Calibrator generates Elemental Mercury
Calibration gas.
•Daily span checks are required with elemental
Mercury.
•CAMR required a “Weekly Integrity Test” with
Oxidized Mercury.
•Thermo
provides the “Mercuric Chloride Generator” for this test.
This device converts or “Oxidizes Elemental Hg into Oxidized
Hg”.
•A 3-point Oxidized Linearity is
required for initial certification of Hg CEMS.
