High pressure differential scanning calorimeter DSC 204 HP
High pressure differential scanning calorimeter DSC 204 HP
Product details
In practical applications, many physical processes and chemical reactions are affected by gas pressure. Therefore, it is often necessary to conduct DSC experiments while maintaining a certain pressure.
NETZSCH has developed a high-pressure differential scanning calorimeter DSC 204 HP, which has a sturdy gold-plated measuring cell and can perform experiments under various atmospheres such as O2, N2, Ar, He, H2, CO2, CH4, etc. under high pressure. The pressure range can be from vacuum to 15 MPa (150 bar), and the maximum temperature for testing can reach 600 ° C. If equipped with a liquid nitrogen controller CC 200 L, the minimum temperature can reach -150 ° C.
The sample atmosphere can be static or dynamic. The electronic pressure control device and precise blowing airflow regulation enable the experiment to have superior accuracy and repeatability. The DSC 204 HP has good safety performance and meets all safety requirements for high-pressure experiments.
The DSC 204 HP is currently the highest working pressure DSC system on the market and the only DSC system capable of measuring negative temperature and high pressure. As a result, the product won the Global R&D 100 Award immediately after its launch.

Oxidation behavior of artificial blended oil
The figure shows a study on the oxidation behavior of an artificial blended oil. The sample size is 3.0 ± 0.1mg, the heating rate is 2K/min, and the test is conducted under an oxygen atmosphere (100ml/min) and a certain pressure. The results indicate that as the oxygen pressure increases, the timing of oxidation behavior occurs earlier, meaning oxidation begins at lower temperatures.
