Description

Uses

The Accelerating Rate Calorimeter is capable of real-time monitoring and recording of critical parameters such as temperature, pressure, and heat release during the reaction process. It provides essential safety assessment data for the development, production, storage, and transportation of chemicals. Its high-precision sensors and advanced data processing system ensure the accuracy and reliability of the test results, making it an indispensable safety assessment tool in the fields of chemicals, pharmaceuticals, and energy.

  • Accurately simulates adiabatic conditions to ensure the authenticity of test results.
  • High-precision sensors capture minute heat changes, ensuring reliable data.
  • Wide temperature measurement and control range to meet the testing needs of various samples.
  • Real-time monitoring of multiple parameters for a comprehensive understanding of the sample’s reaction state.
  • The preferred choice for chemical safety assessment, effectively preventing the risk of production accidents.

How it works?

The instrument creates a highly adiabatic testing environment, ensuring precise monitoring of the thermal decomposition behavior of chemical samples during the heating process without any external heat exchange interference. During the test, the adiabatic calorimeter can record key parameters such as sample temperature, pressure changes, and heat release rate in real-time. These data are crucial for assessing the thermal stability of chemicals, predicting their decomposition temperature and products, and analyzing potential safety risks.

The Accelerating Rate Calorimeter (ARC) offers several testing modes:

  • Constant-Rate Scanning Mode: Quickly identifies the initial reaction temperature and other basic thermal characteristics of a substance.
  • Isothermal Mode: Analyzes the thermal characteristics of a substance when exposed to a constant temperature over an extended period.
  • HWS (Heating-Waiting-Searching) Mode: Determines thermokinetic parameters under adiabatic conditions.

Q&A

How much sample should be loaded into the ARC sample cup for adiabatic thermal stability analysis?
Adiabatic calorimeters are theoretically capable of obtaining a complete thermal runaway curve under true adiabatic conditions. However, since the sample is in contact with the calorimeter's sample cup, some energy will be transferred to the cup walls, meaning the sample cup also has a heat capacity. The heat inertia phi is defined to quantify the energy transferred to the container. To directly obtain the exothermic curve under adiabatic conditions, the ARC sample loading should be as much as possible, but it is important to ensure that the reactor does not rupture due to excessive pressure within the test temperature range. Therefore, before conducting an ARC test, it is advisable to use other equipment to measure the pressure generated by the material's decomposition.
How to choose the type of ARC sample cup?
To accommodate different test materials, adiabatic calorimeters are designed with sample cups made from various materials, such as 316 stainless steel, titanium alloy, Hastelloy, and glass. When selecting a sample cup, the following requirements should be met: The test material should be compatible with the sample cup material. For multi-component mixtures, the compatibility of each component with the sample cup material should be verified. This can be done by consulting literature or conducting experiments to establish a compatibility table for common materials.
