Differential scanning calorimetry. The study of the heat capacity of materials, thermal effects of phase and chemical reactions at high pressures
With the high-pressure Differential Scanning Calorimeter, DSC 204 HP Phoenix, thermal effects in a sample can be analyzed in the pressure range from vacuum to 15 MPa (150 bar) and at temperatures from -150°C to 600°C, depending on the type of gas. The sample chamber atmosphere can be static or dynamic. The electronic pressure monitor and control, along with exact regulation of the purge gas flow, provide for excellent accuracy and reproducibility of the measurement results. The proven CC200L for liquid nitrogen cooling is available for the low-temperature range.
High-Pressure DSC 204 HP Phoenix for the most varied applications
• Determination of vapor pressure and evaporation heat.
• Separation of reactions with overlapped evaporation.
• Measurement of adsorption and desorption, e.g. on metallic compounds.
• Oxidation stability of oils, fats and lubricants.
• Curing of thermosets, e.g. phenolic resin.
• Vulcanization of rubbers.
• Hydration of unsaturated fatty acids.
• Both DSC measurements under ambient and under high pressure.
