Highlights
- Gold amalgamation procedure measures a Hg fraction in between Hg0 and TGM.
- 10–75 % of HgII is recovered as Hg0 by the Tekran 2537 analyzer.
- HgII is lost through adsorption and inefficient thermal desorption of Hg from gold.
- Thermolyzer quantitatively converted HgII to Hg0 to enable a TGM measurement.
- Tekran 2537B models measured 1.5 times higher Hg concentrations than 2537X models.
