差示扫描量热法(DSC)是使用最多的热分析技术。 差示扫描量热仪(DSC)测量样品由于物理和化学性质的变化而发生的焓变与温度或时间的关系。

 

DSC采用创新型DSC传感器,其中配备120对热电偶,确保具有无可比拟的灵敏度与出色的分辨率。 测量原理差示扫描量热法(DSC)会将来自样品的热流和传感器参比侧之间的温差测量为温度或时间的函数。

 

差示扫描量热法的物理特性

当样品吸热或放热时,会由于熔化、结晶化、化学反应、多晶型转变、蒸发和很多其他过程等热效应而引发热流差异。 例如,玻璃化期间的具体热容量和热容量的变化也可从热流差异中测定。

 

温度范围与降温选件

您可以根据您希望测量所在的温度范围,按个人要求调整系统。 IntraCooler是一种仅需使用电源的密封系统。 因此在不希望存在液氮,或者液氮不可用的地点具有明显优势。 液氮冷却系统由于可使您在整个温度范围内进行测量,因此具有更高的灵活性。

得益于One Click™启动试验与内置的气体处理功能,体验极致的易用性。 设计巧妙通过出厂耐久性测试的自动进样器,采用单轴移动和灵活的搬运坩埚,可全天候提供高效可靠的常规操作。
