PS Analytical Millennium Merlin (cold-vapour atomic absorption spectrometer; CV-AFS) with high performance liquid chromatography (HPLC) interface: allows mercury speciation and quantification down to 1 part per trillion (ppt). Samples include natural or synthetic waters, sediments/soils and biota tissues.

Ability to produce mercury radioisotope tracers via our OPAL research reactor and use radiotracers under controlled laboratory conditions in our aquatic lab and greenhouse. Available as radiotracers of Hg0, HgCl2, HgS (metacinnabar) and MeHg (methyl mercury) for a range of research applications) to determine mercury bioaccumulation and retention kinetics in living organisms. Imaging of mercury radiotracers using photostimulated luminescence (PSL) autoradiography to provide detailed understanding of biodistribution of mercury within plant and animal subjects post euthanasia.

Australian Synchrotron (multiple beamlines): 1) Elemental mapping (including Hg) to 1 µm spatial resolution in solid sections (sections of cores, soils, biota etc.) using the X-ray Fluorescence Microscopy (XFM) beamline. Hg detection limit in the ppm range; 2) X-ray Absorption Spectroscopy (XAS) beamline: mercury speciation of solid-phase samples (to determine organic and inorganic mercury species).
