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. For more videos, please subscribe to NanoWorld. Thank you.

Its helpful, you earned a subcription. Thanks!
Nice work!! You earned a subscription.
Una vez mas gracias por el tutorial, la canción se quedo como tema musical del canal jeje
Congratulations for the initiative. Wonderful, beautiful work. Learning and enjoying the sound, thank you.
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
The two tangent lines were to determine the temperature at which the thermodynamic events i.e. Fusion and crystallization started.
Once the temperature is defined, then I just directly look to the corresponding value at y-axis for the specific heat capacity.
Please post a video on how to calculate different thermal parameters using tga/dtg/dta plot
Hats off sir. Great
very good Presentation...
Glad you liked it
Hi, great work, thanks for that.
A question, can we determine the activation energy from DSC curve using origin?
Thanks
Thank you for the informative video! Is the specific heat capacity calculation performed based on a baseline subtracted DSC data?
12:30 is important one.
Thank you, thank you and thank you so very much
Very nice video 👍👍
I will appreciate it if you explain why the MnO2 melting is exothermic.
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???
How can we find Glass Transition temperature from DSC curve using origin?
Hello sir, can you please tell me, how do I calculate glass transition temperature from DSC curve ?
I really thank you a lot, you saved me !!
Hi, great work, thanks for that
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.??
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?
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?
why don't you use kelvin when calculating the specific heat capacity?
Como acrescento a linha F(x) no oringin, no meu não tem! Obrigada
in the sense of the Amorphous one? can you please make another video on it to study amorphous material as well through Calorimetry i-e., finding Tg and fictive temperature etc etc...? thanks in advance
thank you very much. can you please explain why the weight is given in mg but on the graph of specific heat capacity at 25.04 min the unit is in gramm?
Thanks a lot. Great work.
Is it possible to calculate solid fractions with respect to temperature through DSC/DTA curves? Also, please let me know about activation energy determination through DSC plots.
Hello, I would like to ask if the time used to find the specific heat capacity is the Δt check？
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.
@Nanoworld 14:33 why the ratio of column d / column c is multiplied -1 value?
very nice video but i got stuck in integrating the peak and finding value of Enthalpy. I am using origin pro 8 in this peak analyzer and dialog box does not work as yours. If anybody has idea then please help me out. Thanks!1
great work; how to calculate activation energy from DSC using origin?
Very difficult to follow. Would have been great having less distracting music and some spoken information.
Thank you for the suggestion
wow... thank you
Fantastic ... Go ahead ....
If sophisticated TGA and DTA for thermal decomposition of solid are not available. How can you construct it locally if quartz, potentiometer, travelling telescope etc are given
which functions you used at 33.38 (to create shade-like lines in the area), 36.09 (to do a snapshot like job of the Cp curve) and 36.14 (to insert that snapshot-ed portion into the main DSC curve)?
sir i have data in heat flow (normalized) W/g and weight %, tempertaure degree celcius. how can I calculate all these parameters using this data
Excellent video thanks! I just wanted to ask. As you multiplied heat flow data to (-1) the zones of inset and offset must change, right? or am I making a mistake
Hi, thanks for the video. my y axis is in uV/mg. is there any method that I can convert my y axis to mW/mg?
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
merci beaucoup pour cette vidéo , mais j'ai trouvé une probléme car je ne sais pas comment determiner le taux de cristanilité car l'enthalpie de cristalisation est supérieur à celle de fusion donc impossible et cette résultat aussi est similaire que vous avez trouvez ( delta Hm=22 et delta Hcc= 24)DONC COMMENT VOUS AVEZ CALCULER LE TAUX DE CRISTALINITé svp ??
Hi Nanoworld , it's urgent can you please tell me how to convert DTA data from uV to mW as i have to do the dta analysis of a sample how can we predict which salt we are dealing if we have a unkown sample
this is so helpful. Can you please help me as I have 3 column data (time, temperature, and heat flow w/g) weight is not provided.
If you don't have a weight column that's OK. A fixed weight will be written somewhere in your data. If fixed weight is also not present (which is not possible) then you should ask the operator about the weight of your sample.
How to calculate crystallinity?
can we choose baseline? then how to choose?
Can this method be used to calculate the specific heat capacity of nano-enhanced phase change material?
Of course yes.
Hey can you tell me how to download this software
