Thank you so much for sharing your knowledge. I really liked your explanation, very didactic. I was trying to learn how to calculate peak area in a TPR analysis.

Thank you for sharing! I was looking for a good explanation to find and calculate the area under de curve. I’m with spectres of Raman spectroscopy 🙏🏻👏🏻👏🏻

[@SAYPhysics]

Thanks for your feedback! I'm glad the tutorial was useful for you in your Raman spectroscopy work. If you have any more questions, feel free to ask.

How can I do it for several curves on the same graph?

Please see the following videos for doing it for many curves at once. Thanks kzbin.info/www/bejne/Z4vMdX1pg7-hgpo kzbin.info/www/bejne/jYnCiWaOocd-iKM

hi, the area that the program reports it is the area under the curve or it is the entire yellow rectangle?

[@SAYPhysics]

Tye value gives area under the curve, while the rectangle area encloses the curve for calculations. Thanks

[@Yamayuukabkunggg5655]

Excuse me, If i have broad band like a raman spectrum of glass, I also use this way or not ? 🙇🏻‍♀️ Thank you

[@SAYPhysics]

Thank you for your comment! Yes, the procedure for finding the area under the curve remains the same, regardless of the specific broadband spectrum, such as a Raman spectrum of glass. The method I outlined can be applied universally to determine the area under curves in various contexts.

Can we calculate AUC for line graph using same method as shown in video?

[@SAYPhysics]

Yes, it is possible to calculate the area under a straight line. The area under a straight line is simply the area of a rectangle, and you can calculate it by multiplying the length of the line (base) by its height (the distance between the line and the x-axis). The formula for this is: Area = Length × Height So, for a straight line, the area under the curve is straightforward to calculate. Thanks

[@asneelasheshlal6485]

thanks for your professor. I have emailed you my solutions of AUC and the raw data which I used. Can you check and let me know if I had done it coreectly, please.@@SAYPhysics

[@SAYPhysics]

@asneelasheshlal6485 I checked it but it doesn't seem correct. I'm suggesting you my following tutorials for doing the task. Thanks kzbin.info/www/bejne/Z4vMdX1pg7-hgpo kzbin.info/www/bejne/en7Wc619eLN7h80 kzbin.info/www/bejne/qqvMiYWMab2AZs0 kzbin.info/www/bejne/npnLYpeLoc5qeKs

hi, Can we find only the peak's area instead of the whole yellow rectangles?

[@SAYPhysics]

Yes. Thanks

[@obedboakye4140]

when i use this method and other method for finding the area, it gives two different values. The other method is executed by using the integrate option under gadgets. Any comments on this?

[@SAYPhysics]

Thanks for your comment! It's not uncommon to get slightly different area values when using different methods to calculate the area under a curve. In the video, I demonstrated one specific method using OriginLab. The "integrate" option under gadgets likely uses a different approach, which can lead to slight variations in the results. The precision and algorithms can differ between methods. If you need precise results, it's good to understand the specific algorithms used in each method and how they handle calculations. Feel free to share more details if you'd like to discuss this further!

[@elizabethalbineda5502]

And what are the units for the area reported in the program?

[@SAYPhysics]

It's not like area in m2, it depends on what we plot on y and x axes. Thanks

How is the area LESS than the peak height?

[@SAYPhysics]

Area under a curve represents the total accumulation of values within that region, not just the peak height. In some cases, the area under the curve may be less than the peak height because the curve descends rapidly after reaching its peak, resulting in a smaller total area. Additionally, the shape of the curve and its distribution of values play a significant role in determining the area under the curve. Thanks

[@mehranalam1274]

And sir why we can’t use the option fix width for all peaks instead of auto. And sir can we consider this calculation exactly correct, as we know origin have no link with pdf data base how they can show us exact peak area.

[@SAYPhysics]

You're right somehow. I'll suggest, you watch this video too to understand the roots of it. Thanks kzbin.info/www/bejne/npnLYpeLoc5qeKs

Nice video sir , is the calculated area is under the yellow highlighted one which is obviously large or it is exactly the area under the curve I mean the peak area?

[@SAYPhysics]

Yes, it is exactly the highlighted one (yellow color). Thanks

How to calculate volume?

[@SAYPhysics]

Thank you for your question! In 2D, you can only calculate the area under the curve. To calculate the volume, you would need a 3D dataset. OriginLab has tools that can help you perform volume calculations for 3D surfaces. You can use the 'Volume of Surface' tool under the 'Analysis' menu for this purpose.

[@akashanand50]

@@SAYPhysics but sir I am seeing in the analysis part but there is no volume surface option.
