The cost‐effective Calorimetria por taxa de Aceleração (ARC)The method describing isothermal and adiabatic test procedures used to detect thermally exothermic decomposition reactions.ARC®® 244 is designed to safely measure the amount and rate of heat release associated with the processing or storage of chemicals within a container volume between 1.5 ml and 8.5 ml.
This is the calorimeter which uses the same design as the first ARC®® system developed by DOW for those customers interested in keeping the same platform.
This information is vital in developing and evaluating processes to ensure safe operation and to prevent Thermal runawayA thermal runaway is the situation where a chemical reactor is out of control with respect to temperature and/or pressure production caused by the chemical reaction itself. Simulation of a thermal runaway is usually carried out using a calorimeter device according to accelerated rate calorimetry (ARC).thermal runaway which can have devastating effects.
The Accelerating Rate Calorimeter 244 (ARC®® 244) technology is integral to designing inherently safer batteries as well as measuring energetic materials used in such products as explosives, propellants, and air bags.
