Heat flow calorimetry
WebHeat flow is proportional to the heat difference of heat sink and holders. Heat sink has the enough heat capacity compared to the sample. In case the sample occurs endothermic or exothermic phenomena such as transition and reaction, this endothermic or exothermic phenomena is compensated by heat sink.

WebThe system offers two modes; Heat Flow Calorimetry (HFC) or Power Compensation Calorimetry (PCC), allowing you to choose which mode is suitable for your process. HFC is generally used for reactions where the heater may have an effect on the chemistry since the dip in heater is not used during the reaction. Webmeasure heat flow, the movement of heat in and out of a sample, directly. This instrument uses a feedback loop to maintain the sample at a set temperature while measuring the power needed to do this against a reference furnace. This allows for very precise control of temperature, very accurate enthalpy and heat capacity measurements,
