Highly versatile, miniature chemical reactor, it measures the thermal and pressure properties of exothermic chemical reactions.
Calorimeters are based on one of three different methods. The temperature change method involves the use of a measuring cell to determine the heat shift of a reaction taking place in the calorimeter.
The power compensation method involves a reaction and a heat source being kept at the same power, resulting in a heat change that is equivalent to. Non-adiabatic calorimeter (NAC) allows to determine accurate values of the specific absorption rate (SAR) from colloidal dispersions of magnetic nanoparticles subjected to alternating magnetic fields (up to kHz and 48 kA/m) and/or infrared laser that purpose, the calorimeter system minimize thermal exchange losses while integrates sample volume into a space where homogenous.
