Calorimetry and reaction monitoring



Calorimetry is a valuable tool for the process chemist with applications in applications in Process Analytical technology (PAT), as well as wider use in day-to-day laboratory work.  Common techniques include heat flow calorimetry and power compensation calorimetry.

Reaction monitoring

Reaction monitoring by studying the thermal responses from the reactor (the temperatures of the reactor, circulator, coolant in and coolant out can all be used) can provide important information about the process of a reaction.

Atlas can simply and easily monitor and log all of these parameters to generate reaction monitoring information.  As with all Atlas data these can be downloaded to a USB stick in csv format or recorded directly through the PC software.

Calorimetry

Reaction calorimetry is widely used to investigate reaction enthalpy changes for safety assessments however the data generated by a reaction calorimeter has wide application in areas such as reaction optimisation, kinetic studies and PAT.

The heat being produced by any reaction is directly proportional to the rate of reaction hence the ability to generate kinetic data.  In PAT studies the advantage of calorimetry is the non-invasive and non-selective nature of the measurement.  Non-selective measurements are advantageous as they are able to produce data when the system deviates from expected behaviour (the data is from gross system behaviour).  Non-invasive measurements have the advantage that the measurement does not change in any way the system which is being measured.
