Comparison of WDS and EDS Rare Earth Element Analysis

X-Ray Mapping Using Multiple-EDS and WDS Detectors

High quality x-ray mapping (XRM) has been used for over 30 years by experienced wavelength dispersive spectroscopy (WDS) operators. Manufacturers have been developing similar techniques using energy dispersive spectroscopy (EDS) over the last 20 years. This has been generally unsuccessful due to a number of problems such as poor computer specifications, cost, time to map and generally poor peak...

trace and rare earth element geochemistry of croatian thermalwaters

concentrations of 42 trace elements, including rare earths, in croatian thermal waters wereinvestigated. originating from different parts of croatia, i.e. different types of aquifers, studied thermal watersprovide insight into the range of concentrations of broad spectrum of elements in croatian thermal waters.covering a wide range of temperature (30 - 92 °c), studied thermal waters are general...

Overland Flow Using Rare Earth Element

14 15 Rare earth element oxides (REOs) have excellent potential for use as tracers in 16 erosion studies. Using laboratory and field experiments we aimed to develop and test 17 a simple application method for spreading REOs and to use REOs to determine the 18 source of sediment to concentrated overland flow paths. 19 Tracks left by farm machinery (tramlines) in fields act as concentrated flow 2...

Communal metabolism of methane and the rare Earth element switch.

Metabolism of methane is an important part of biogeochemical cycling of carbon. Methane is also a major contributor to climate change. A specialized group of microbes that consume methane, the methanotrophs, represent a natural filter preventing an even faster accumulation of methane in the atmosphere. Methanotrophy can proceed via both anaerobic and aerobic modes. The anaerobic methanotrophs, ...
