Reaction calorimetry is used to monitor the heat release rate, as a reaction proceeds.
The technique is particularly useful as it makes this data available while using fairly normal (conventional) stirred glass or metal vessels.
This means that chemistry can be performed realistically without any need to alter the procedure and the data is therefore directly applicable to larger scale processes without the need for modification.
HEL has pioneered the use of power compensation calorimetry as a particularly useful technique for generating this data.
This has several advantages of the more widely used heat flow method: fast accurate temperature control; results are intuitive, displayed in real time as the experiment proceeds; experimental procedure is straightforward, requiring no calibration steps and making experiments faster and simpler.
For the reasons listed above, power compensation is attractive to both process development chemists and safety specialists alike.
The former find the ease of experimental procedure and clarity of results appealing - kinetic information is made available at virtually no cost of extra time or calculation effort.
HEL includes power compensation on the Simular reaction calorimeter.
This typically supplied in volumes 0.5 to 2litre.
In addition, multiple vessel systems with reaction calorimetry are also supplied - for example four or even eight vessels in parallel at volumes from around 75 to 350ml.
