Abstract: A heat flow rate measurement method for use with a differential scanning calorimeter sensor is provided. The method includes calculating a heat exchange between a plurality of sample containers and a reference container placed on a plurality of sample calorimeter units and a reference calorimeter unit, respectively, and determining a heat flow rate of samples within the sample containers using the calculated heat exchange between the plurality of sample containers and the reference container. A multiple sample differential scanning calorimeter sensor and calorimeter system are also provided.

Abstract: A heat flow sensor for a heat flux differential scanning calorimeter comprising twin thermopiles. The thermopiles each comprise positive and negative thermocouple alloys and electrically insulating ceramic components. Diffusion bonding is used to form thermocouple junctions in the thermopiles between the positive and negative thermocouple elements, and to attach the thermocouple elements to the ceramic components.

Abstract: A dynamic mechanical analyzer and a sample fixture for a dynamic mechanical analyzer that attaches fixed clamps in the sample fixture to a rigid frame using mounts that are compliant in the direction perpendicular to the sample displacement but which at the same time are resistant to rotation about the transverse direction of the sample. The compliant mounts include a pair of flexures that are attached to each fixed clamp and to the frame of the sample fixture. In an embodiment, the pair of flexures are thin flat members such that each pair constitutes two parallel leaf springs. The flexures flex to allow the fixed clamps to move perpendicularly to the sample displacement, but at the same time prevent rotation of the fixed clamps.

Abstract: A method of operating a differential scanning calorimeter wherein errors in the heat flow rate measurement are reduced by operating the calorimeter in a quasiadiabatic mode and by employing a heat flow rate measurement algorithm that includes the leakage heat flow rate. The temperature of the DSC enclosure is controlled independently of the temperature of the measuring system, which allows the temperature difference between the sample and reference containers and the enclosure to be minimized, thus minimizing leakage heat flow.

Abstract translation: 一种操作差示扫描量热计的方法，其特征在于，通过在准半辐射模式下操作量热计，并采用包括泄漏热流量的热流量测量算法来降低热流量测量中的误差。 DSC外壳的温度独立于测量系统的温度进行控制，这样可以使样品和参考容器与外壳之间的温差最小化，从而将泄漏热流最小化。
