本文介绍了一种连续微流控量热计，用于测量非常危险的高放热化学反应的动力学和焓。主要思想是使用微流控芯片，在共流或液滴流中，微通道充当化学反应器。热电堆（珀尔帖元件）测量化学反应过程中散失的全球热通量。在热电堆和反应器之间放置一个高导热板，以避免严重的温度梯度，并让大部分热流通过该板。由于微通道尺寸，只需要少量的产品。
This paper presents a continuous microfluidic calorimeter to measure kinetics and enthalpy of very dangerous, highly exothermic chemical reactions. The main idea is to use a microfluidic chip, in co-flow or droplet flow, where the microchannel acts as the chemical reactor. A thermopile (Peltier element) measures the global heat flux dissipated during the chemical reaction. A highly thermal conductive plate is placed between the thermopile and the reactor to avoid severe temperature gradients and to let most of the heat flux go through this plate. Because of the microchannel dimensions only a small amount of products is required.
