Equipments

Conventional” High Temperature – High Pressure facilities :

This platform houses facilities to reproduce pressure and temperature relevant for Earth’s crust and superior mantle. It consists of conventional devices (ovens, autoclaves and piston-cylinders) that are typically found in HT-HP laboratories. These devices are used to determine, among other, phase equilibria, solubility laws, partition coefficients or to measure physico-chemical properties at high pressure and high temperature.

Rock Deformation Laboratory

The rock deformation laboratory, directly derived from the conventional HP-HT platform, includes equipment capable of imposing anisotropic pressures on samples and thus deform them. This equipment allows the study of rheological laws and deformation mechanisms of rocks and minerals. The Laboratory is equipped with :

Micro/nano-fluidic laboratory

This experimental platform, equipped with high resolution microscopes (upright and inverted) and Raman spectrometer, is devoted to the microfluidic technics: cut-edge optical observation as well as chemical and structural analyses of the Lab-on-Chip.

Such microfluidic approach allows to isolate and investigate the challenging multi-scale and multi-physics processes such as flow microdynamics, mass transfer, solubility or storage, which occur in porous media and geological reservoir.
