Calorimetry - PHITEC II

Sample cells
Test cells can be made of glass or a range of metals. For screening tests, metal or glass cells (≈10ml) may be used, but for detailed studies of reactions, larger (100 to 120ml) cells are appropriated.

Sample agitation
Agitation of viscous liquids or multi-phase samples can be performed by use of mechanical agitation driven by a conventional electric motor. This design can be used on thin-walled test cells and is often essential if reliable design data is to be generated.

Sample addition
The sample can be loaded into the test cell at any stage: prior to placement in the containment vessel, whilst in situ, or during the experiment.

Temperature/pressure measurement
A fast-response, type k thermocouple is placed inside
the test cell directly in contact with the sample, range 0 to 500^oC. Maximum pressure is typically 138 bar (2000psi).

Exotherm detection-sensitivity
In general, exotherm detection down to 0.02°C/min.
Heaters can track rates of over 200°C/min.
