I have some raw DSC test data and I need to do baseline correction. I don't know how should I do it. I would appreciate it if someone can help me with this.

Hello Faezeh Iranmanesh
You can use different software, for example Microsoft Excel. The most easiest way would be to calculate a linear equation, by using two points (in your case the first and last value of your data). You can use the formula of this trendline/baseline to correct your data. To do so you have to substract your original values from the trendline values. The result will be a corrected baseline. If you want to do it in a more detailed way, you can also use several trendlines.
I hope this helps!
Best regards Paul
Hello! You can use Origin for that ( https://www.youtube.com/watch?v=yPac-12JhrM ). I could help you, if you need. Kind regards, Julián.

Thanks for your answers. I have a DSC curve. I did the baseline correction for this curve in two different ways using Origin. I don't know which one of them is the correct way to do this. I have attached the original DSC curve as well as the two different baseline corrections. Do you have any idea that which one of them (if any) could be the correct baseline?
Dear Faezeh Iranmanesh
I am in agreement with the second baseline (I am attaching the file).
Remember to extract this for obtaining the real curve.
With kind regards,
Julián Sánchez.
Dear Julián E. Sánchez-Velandia
Thanks for your answer. This makes sense.
Regards,
Faezeh
The quality of the baseline (better to say "empty pan line") method depends very much on the quality of the DSC: The baselines of several runs (with same parameters) must be one on top of the other always before you successful can subtract the baseline from the sample run. The method you use (i.e. the software of the DSC or any mathematical or other evaluation software) does not matter.
