Differential microcalorimetric analysis procedure and device for substance that can contain crystals, e.g. chocolate, has adjustable temperature zone and sampler

摘要

The microcalorimetric analysis and measuring device has an adjustable temperature zone with a regulator, a sampler (4) and a system for transferring the sampler from the sample taking zone to the adjustable temperature zone, where the temperature of the sample, measured by a Peltier effect module, is compared with a reference sample. The sampler transfer system comprises a motor (9), a threaded shaft (1) and a coupling, preferably of meshing gears (8a, 8b).
