摘要： The invention relates to a flow microcalorimeter wherein the reactant fluids are injected in one tubular flow chamber and reacted while mixing and flowing therethrough and a heat exchange means is associated with the tubular flow chamber wherethrough a fluid is circulated in a reverse flow direction. Measurements can be made in either the adiabatic or the isothermal mode depending on the relative flow of the reactant fluids and the heat exchange fluids. In some applications, such as when very fine measurements are required, thermal effects unrelated to the mixing can be cancelled out by introducing the already mixed and reacted fluids into a similar tubular flow chamber with a similar heat exchanger, this arrangement including a differentially coupled temperature sensing means associated with the outlets of said heat exchange means.
