Abstract
An open calorimetry system comprising an active vessel, a passive vessel, and a first and second heat flux detector in thermal communication with the active vessel and passive vessel respectively. A thermal reservoir is connected to the first heat flux detector and the second heat flux detector, wherein data from the heat flux detectors is used in a differential analysis resulting in an energy measurement of an article in the active vessel.
Claims19
A calorimeter comprising:
- an active vessel;
- a passive vessel;
- a first heat flux detector connected to the active vessel with a first conductor;
- a second heat flux detector connected to the passive vessel with a second conductor;
