【求助】DTA熱分析
|
|
各位蟲友: 大家好!有哪位大俠知道DTA和DSC的的區(qū)別,從部分文獻(xiàn)中可得到DSC的衍射峰面積就是本次相變所釋放的潛熱,那么DTA的衍射峰面積又有什么涵義呢? 謝謝! |

In DTA, the heat flow to the sample and reference remains the same. The variable is the temperature difference between the sample and reference. When the sample and reference are heated identically, phase changes and other thermal processes cause a difference in temperature between the sample and reference In DSC, the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. Both the sample and reference are maintained at nearly the same temperature throughout the experiment. curve: DTA: delta T vs T. The T is the temperature of reference substance. unit: both are degrees C. DSC: Heat flow difference versus T. T is the temperature of reference substance. unit: y axis is mW/mg. x axis is degree C. DSC is more accurate and powerful. |
