Comparison of Hg LIII and Se K near-edge spectra of selected standard species. Most species were measured as dilute (ca. 1 mM) aqueous solutions buffered at physiological pH (7-7.5) in the presence of 30% v/v glycerol using X-ray fluorescence detection. Exceptions were nano-HgSe which was run as a colloidal suspension in buffered water with 30% v/v glycerol, HgSe, HgO and β-HgS which were run as solids by monitoring transmittance, and CH3HgCH3 which was run in isopropanol solution due to its low water solubility.
