DSC Analysis Through OriginLab - Enthalpy and Specific Heat Capacity - 16

Differential Scanning calorimetry (DSC) is a very sensitive and powerful technique that gives very detailed information about the thermal properties of a material. In this video, I have shown a detailed method for the calculation of thermodynamic parameters from DSC data using OriginLab software. If you have any questions, ask them in the comment section below.

Its helpful, you earned a subcription. Thanks!

Hi, great work, thanks for that.
A question, can we determine the activation energy from DSC curve using origin?
Thanks

Una vez mas gracias por el tutorial, la canción se quedo como tema musical del canal jeje

Thank you for the informative video! Is the specific heat capacity calculation performed based on a baseline subtracted DSC data?

[tolgatamer]

I am perplexed in the specific heat capacity calculation. First, you need to apply the ASTM - Sapphire method to get a baseline-corrected result. Secondly, I did not understand why you multiplied heat flow by time? In DSC measurements, a fixed temperature rate should be applied. Why did you apply (time/temperature) for each measurement? Is there a specific reason for that?

[snehalholey]

I am just having doubt as I am also not having weight column in my data but fixed weight is there, so can I use that same fixed weight at all temperature as in your data your weight is changing with temperatures??? And if we r not getting that column then may be they have already given that heat flow in J/g unit then how to understand that thing???

Please post a video on how to calculate different thermal parameters using tga/dtg/dta plot

Hello sir, can you please tell me, how do I calculate glass transition temperature from DSC curve ?

[ishikasharma]

How can we find Glass Transition temperature from DSC curve using origin?

[erichuang]

Thanks for your very helpful video. I don't know why the heat capacity is based on the intersection of two tangent lines on the Cp-T curve, rather than looking at the corresponding value of the function on the Cp-T curve

[delin-fcxy]

Hello, I would like to ask if the time used to find the specific heat capacity is the Δt check？

[camillalourencovieira]

Como acrescento a linha F(x) no oringin, no meu não tem! Obrigada

[dhewaedikresnha]

why don't you use kelvin when calculating the specific heat capacity?

[ayeshagul]

Hello. Thank you for your valuable lessons. May i know how to create DSC graph containing three heating cycles in one plot? I tried alot but could not figure it out. Means i have run three heating cycles (-60 to 200, then -60 to 250 and then -60 to 300C). Will i include the cooling data too or just the heating rate? I am very much confused. Would be grateful if you could help me in this regard.

[polk]

A question, why specific heat capacity is directly calculated by (Heat flow*Time)/(Mass*Temp)? It seems like DSC records the heat flow data per 6 second. So itn't it should be calculated by (Heat flow * 6 seconds)/(Mass* delta T), that is Joules within 6 second divided by mass and temperature change?

[shahzadahmed]

Nice video. How did you measure the weight here? Because we usually check the weight loss percentage. How the weight is increasing with temperature? Weight should decrease with temperature as there is decomposition of the material but here it is increasing.??

@Nanoworld 14:33 why the ratio of column d / column c is multiplied -1 value?

[shilpabhoomi]

Hello.... How do u get this weightin mg from DSC .xls sheet... i did not get weight in mg from DSC ...which model DSc intrument is this...can u plz post the machine model name
