    • A calorimeter assembly comprising Dewar flask means, a sealed vacuum container positioned in the bottom of the Dewar flask means and a sealed sample holding container positioned in the vacuum container provided with sump means and a gas removal tube connected to the sump means; the gas removal tube extending toward the top of the Dewar flask means and having a portion located outside of the vacuum container which portion includes spiral windings, and means for introducing fluids into the Dewar flask means and said sample container and means for regulating pressure in the Dewar flask means and for measuring gas flow from the sample container. The invention also includes the method of measuring heat loss by use of the calorimeter assembly set out in which the volume of gas emitted from the gas removal tube is compared with that volume of gas emitted for a known heat input.
    • 包括杜瓦瓶装置的量热器组件,位于杜瓦瓶装置底部的密封真空容器和位于真空容器中的密封样品保持容器,该真空容器设置有贮槽装置和连接到贮槽装置的气体去除管; 气体去除管朝向杜瓦瓶装置的顶部延伸并且具有位于真空容器外部的部分,该部分包括螺旋绕组,以及用于将流体引入杜瓦瓶装置和所述样品容器的装置以及用于调节 杜瓦瓶装置用于测量来自样品容器的气体流量。 本发明还包括通过使用量热器组件来测量热损失的方法,其中将从气体去除管发出的气体体积与用于已知热量输入的气体体积进行比较。
