An Accelerating Rate Calorimeter (ARC®
) is an instrument that
measures a system's adiabatic pressure and temperature response to temperature
and time. The ARC can be used to obtain information about the thermal behavior
of reactions, reaction onset temperature, heat release rate, pressure rise
rate, and amount of condensable vapor and non-condensable gas generated. The
ARC is primarily used for liquid-phase reactive systems. It is also used for
safety/performance evaluation of explosives and propellants. In isothermal
mode, it can be used to evaluate storage conditions.
Building on the calorimetry expertise included in the Differential Scanning
Calorimeter, the Accelerated Rate Calorimeter (ARC®
) instrument has
additional capabilities. These allow performance of experiments requiring low
self heat rate detection with simultaneous pressure measurement, isothermal
aging and gas/solid phase reaction analysis. The ARC has the unique capability
of testing reactive chemicals which result in high pressure generation, as high
as 35,000 psia. Data can be used for reactive system process optimization,
emergency relief system design, self-accelerated decomposition temperature
(SADT) analysis, batch and semi-batch reaction process simulation, and physical
