Originally designed under a IFP (Institut Francais du Petrole) license to study the gas hydrates formation and dissociation, the high pressure version of the ?DSC7 evo offers unique capabilities on the market: on a wide temperature range, from the subambient temperature of -45°C up to 120°C, it is possible to carry out high sensitive DSC measurements under high and very high pressure, up to 1000 bars (14 600 psi). Experiments under gas supercritical conditions, such as CO2, are also available.
The high pressure ?DSC7 evo comprises three elements:
– the highly sensitive microcalorimeter ?DSC7 evo providing a temperature range from -45 up to 120°C,
– a pair of dedicated gas-tight high-pressure cells: they are designed to work up to 400 bars (5800 psi) and to contain 0.5 ml of sample. They are made of Hastelloy C276, which allows the analysis of corrosive fl uids. They can be re-used after a suitable cleaning. Very-high-pressure cells with pressure capabilities up to 1000 bars (14600 psi) are also available on request,
– a specific high pressure gas panel.
