Differential scanning calorimeter DSC 204 HP Phoenix®

laboratoryautomatic

Numerous physical processes and chemical reactions are influenced by the surrounding gas pressure. In practise it is therefore often necessary to conduct DSC measurements under an increased pressure. 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 CC 200 L for liquid nitrogen cooling is available for the low-temperature range. The safety of the high-pressure DSC system has been certified through design tests and is guaranteed during operation by the appropriate safety components. Technical Data Wide pressure range vacuum to 15 MPa (approx. 2140 psi) Exact pressure adjustment (e.g. 10 MPa ± 0.002 MPa) Heating rates 0.01 K/min to 100 K/min Temperature range (depending on the gas type) -150°C to 600°C (at 1 bar) -90°C to 600°C (at 50 bar) -50°C to 450°C (at 150 bar) Measurements in different atmospheres inert: N2, noble gases reducing: H2 oxidizing: O2, CO2, air Exact gas flow regulation up to 500 ml/min SOFTWARE The Proteus®® Software includes everything you need to carry out a measurement and evaluate the resulting data. Through the combination of easy-to-understand menus and automated routines, a tool has been created that is extremely user-friendly and, at the same time, allows sophisticated analysis.
