Quebec Geoscience Centre (QGC): mercury analysis (Hg-AFS), weak acid digestion (HCl 0.3M)
Atomic fluorescence spectroscopy analysis of mercury was performed on the samples. The samples were analysed after weak acid digestion using 0.3M hydrochloric acid. These analyses were done by laboratories at the Quebec Geoscience Centre (QGC).
Atomic fluorescence spectroscopy analysis for mercury (Hg-AFS) was performed using a P.S. Analytical (Merlin Plus model) instrument. Before analysis, digestion of the < 63 μm fraction was completed with the help of a microwave system, CEM-MDS-2000. The partial (HCl 0.3M) and total (H2SO4 – HNO3) extractions were done in Teflon vessel bombs using certified ultra-pure products. The precision (+/- 1.03 ppb) of the results was determined by repeat analysis of internal standards and NBS standards (National Bureau of Standards).
