Highlights
The Accelerating Rate Calorimeter 305 (Accelerating Rate Calorimetry (ARC)The method describing isothermal and adiabatic test procedures used to detect thermally exothermic decomposition reactions.ARC® 305) provides AdiabaticAdiabatic describes a system or measurement mode without any heat exchange with the surroundings. This mode can be realized using a calorimeter device according to the method of accelerating rate calorimetry (ARC). The main purpose of such a device is to study scenarios and thermal runaway reactions. A short description of the adiabatic mode is “no heat in – no heat out”.adiabatic calorimetry data in a safe, controlled laboratory environment.
Accelerating Rate Calorimeters can be used for the thermal analysis of solid or liquid chemicals or for gas/liquid, liquid/liquid, gas/solid, and liquid/solid mixtures. They can also be used for process simulation of batch and semi-batch reactions, fire exposures, emergency relief venting, and physical properties measurement.
The advanced Accelerating Rate Calorimetry (ARC)The method describing isothermal and adiabatic test procedures used to detect thermally exothermic decomposition reactions.ARC® 305 helps engineers and scientists identify potential hazards and tackle key elements of process optimization and Thermal StabilityA material is thermally stable if it does not decompose under the influence of temperature. One way to determine the thermal stability of a substance is to use a TGA (thermogravimetric analyzer). thermal stability. As a highly versatile, miniature chemical reactor, sample can be stirred, material injected, and it can be used for vent studies. The Accelerating Rate Calorimetry (ARC)The method describing isothermal and adiabatic test procedures used to detect thermally exothermic decomposition reactions.ARC® 305 has been designed to use the traditional 10 ml Accelerating Rate Calorimetry (ARC)The method describing isothermal and adiabatic test procedures used to detect thermally exothermic decomposition reactions.ARC® spherical vessel but can also use the larger 130 ml vessel for low Phi or vent testing.
- Fastest Tracking Rate: More reliable data and a wider range of application due to the fastest tracking rate up to 200 K/min
- VariPhi technology : Patented VariPhi technology can realize low phi test even with a small and safe sample size. Effective detection of both ExothermicA sample transition or a reaction is exothermic if heat is generated.exothermic and EndothermicA sample transition or a reaction is endothermic if heat is needed for the conversion.endothermic transitions can be achieved by the versatile operating modes on Accelerating Rate Calorimetry (ARC)The method describing isothermal and adiabatic test procedures used to detect thermally exothermic decomposition reactions.ARC® 305
- Proteus® software: Controlled by the same powerful Proteus® software which user can use to operate all other NETZSCH thermal analysis instruments in the lab.
Accelerating rate calorimetry has been the cornerstone of chemical process safety for the last 30 years. These cases require measuring both the amount of heat released (thermodynamics) and the rate at which it is released (kinetics). This can cause significant increase in sample pressure. The combination of temperature and pressure rise can lead to an explosion. Therefore, AdiabaticAdiabatic describes a system or measurement mode without any heat exchange with the surroundings. This mode can be realized using a calorimeter device according to the method of accelerating rate calorimetry (ARC). The main purpose of such a device is to study scenarios and thermal runaway reactions. A short description of the adiabatic mode is “no heat in – no heat out”.adiabatic calorimeters are generally designed to be much more robust than many other types of calorimeters.
Method
The Accelerating Rate Calorimeter 305 (ARC® 305) simultaneously measures temperature and pressure. The sealed pressure system also allows the user to evaluate the effect of different gas atmospheres on the Thermal StabilityA material is thermally stable if it does not decompose under the influence of temperature. One way to determine the thermal stability of a substance is to use a TGA (thermogravimetric analyzer). thermal stability of the system.
Gaseous reaction products may be analyzed at the end of an experiment to help identify and understand the reaction mechanisms involved.
A single experiment provides data for use in the following:
- Thermal Hazard Evaluation
- Pressure Hazard Evaluation
- Thermokinetic Analysis
User safety is a key objective in the design of model 305. The user is protected by a series of safety systems that are completely independent of the control system. These safety systems work to protect the user in the event that the primary control system fails. Fully computer-controlled and highly automated, the Accelerating Rate Calorimeter (ARC® 305) features a graphical interface that is easy to learn and use.
The system is totally integrated into clean, modern designs in which all routinely used equipment is easily accessible.
