摘要: Strategies based on the principle of heat flow and temperature control were implemented, experimentally tested, to increase sensitivity a Tian–Calvet microcalorimeter for measuring heats adsorption. Here, both heat-flow schemes explored diminish heater-induced thermal variations within sink element, hence obtaining less noise in baseline signal. PID controllers implemented closed-loop system perform actions calorimetric setup. The experimental results demonstrate that strategy provided better stability when compared control. effects stemming from type power supply used also investigated.
