Differential scanning calorimetry (DSC) is a method of thermal analysis for determining the amount of heat released or consumed by a sample at a defined temperature change. For this purpose, a container with sample material and an empty reference container are simultaneously exposed to the same temperature regime. During the investigated process (phase changes and/or chemical reactions), energy is consumed or released by the sample. These exothermic or endothermic processes are mirrored by …

The Environmental Mineralogy Labs are equipped with a very diverse suite of spectroscopic and scattering instruments to determine material chemical composition, structure, surface area and grain size of both synthetic and natural samples. For instance,

• Our powder X-ray diffractometer (XRD) consists of two individual instruments capable of X-ray scattering analysis using both Cu (λ=1.54 Å) and Ag radiation (λ=0.56 Å) in transmission geometry. XRD can be used to analyze both crystalline …

In the laboratory for fluid physics, various devices are used to determine the properties of geothermal fluids: density, viscosity, electrical conductivity, thermal conductivity, heat capacity, sonic velocity.
