Measuring the thermal and pressure properties of exothermic reactions helps identify potential hazards and tackle elements of process optimization and thermal stability. Netzsch’s new accelerating thermal calorimeter, the ARC 254—a miniature chemical reactor— helps accomplish these goals. Its fastest tracking rate of up to 200 K/min ensures more reliable data and a wider range of applications. The instrument can be coupled with VariPhi technology to and provide more methods of operation. Effective detection of both exothermic and endothermic transitions, and sample Cp can be achieved with the unit’s operating modes. It is suitable for chemical, pharmaceutical and battery industries.
