Talk:Differential thermal analysis

Review articles? Textbooks?

It's great that there are so many references for this article. But I wonder if there are any review articles or textbook articles? Since DTA is quite an established method, they are preferable to primary sources in this particular article. --Rifleman 82 14:44, 29 October 2007 (UTC)

Grammatical error

Would somebody please clarify the meaning of the following sentence and/or make corrections; "The area under a DTA peak can be to the enthalpy change and it is not affected by the heat capacity of the sample." (Found in the first paragraph. A reference for this would probably be handy, too.) --Zatnik (talk) 07:44, 25 March 2008 (UTC)

The above sentence and the paragraph it is in was directly copied from the first reference.208.255.163.218 (talk) 00:11, 2 November 2008 (UTC)

It might be usefull it somebody were to scan in on of their DTA specs to give an example of what they look like. --Zatnik (talk) 07:44, 25 March 2008 (UTC)

Factual Error?

Reference 1 is not available anymore, which is why I can't check the reasoning behind the sentence "The area under a DTA peak is the enthalpy change and is not affected by the heat capacity of the sample." To my understanding this statement is absolutely wrong. The definition of specific heat tells that dT = dH / c_p. If reference and sample are supplied with the same amount of heat Q, but have different specific heat, the temperature difference reflects not only on the (transition) enthalpy of the sample, but also on the differences in specific heat. The method that eliminates differences in specific heat from the picture, is differential scanning calorimetry (DSC) that feeds reference and sample with individual heat. Only in DSC, thermogramm integrals translate into transition enthalpies and the first differential into changes of heat capacity of the sample as a function of temperature. Please, check an correct. 79.235.244.31 (talk) 09:37, 9 December 2013 (UTC)
