Easy-to-use reaction calorimetry system
The Atlas HD Reaction Calorimeter is a high-performance reaction calorimetry system that exists for safe, accurate and straightforward thermal analysis of chemical reactions. The system operates in either Heat Flow Calorimetry (HFC) or Power Compensation Calorimetry (PCC) mode, allowing users to select the most suitable measurement method for their process.
Designed for ease of use, the Atlas HD simplifies experiment setup, automates key procedures and enables rapid generation of power and enthalpy graphs.
Heat Flow Calorimetry (HFC) and Power Compensation Calorimetry (PCC)
The system supports two reaction calorimetry methods, each suited to different applications.
Heat Flow Calorimetry (HFC) is generally preferred for:
- Reactions where the heater could influence the chemistry
- Processes involving large exothermic reactions
During HFC measurements, the dip heater is not used while the reaction is taking place.
Power Compensation Calorimetry (PCC) is typically selected when faster results are required, as it does not require pre- or post-experiment calibration.
In both operating modes, you can monitor important reaction parameters in real time.
Automated reaction control
The Atlas PC Reaction Calorimetry Software guides users through experiment setup using an intuitive wizard.
Parameters that can be configured include:
- Reaction temperature
- Reagent dosing quantities
- Expected power level (for example, moderate endothermic or strong exothermic reactions)
- Alarms and associated actions
Once the experiment starts, the software automatically manages the complete process, including:
- Stabilization at the target reaction temperature
- Reagent addition
- Pre- and post-run calibration for HFC experiments
This automation allows experiments to run without user intervention.
Flexible laboratory system
The Atlas HD Reaction Calorimeter is compatible with a range of vacuum-jacketed reactors from 100 mL to 2 L, providing flexibility for different laboratory applications. When reaction calorimetry is not necessary, you can also use the system as an automated jacketed reactor, allowing it to serve multiple purposes within the laboratory.
Fast data analysis and reporting
Following each experiment, the Atlas Reporting Software simplifies data analysis.
The software automatically:
- Includes calibration data
- Compensates for the enthalpy of reagent addition
- Corrects for deviations from isothermal conditions
Power and enthalpy graphs can then be generated with a single click, making post-experiment analysis quick and straightforward.
What is reaction calorimetry?
Reaction calorimetry is a branch of calorimetry that measures the heat released or absorbed during a chemical reaction. It enables chemists to study the thermal behavior and kinetics of reactions on a laboratory scale while working under realistic process conditions, including controlled stirring, temperature, pressure and reagent dosing.
By measuring the energy generated or consumed during a reaction, reaction calorimetry supports process understanding and allows failure scenarios to be investigated safely on a small scale.
