Very helpful. A question is whether there is a criterion or benchmark for comparing the cumulative fitted curve with the original curve. Or, just by "seeing" the difference of two curves can we decide whether the fitted one is good or not.

[@SAYPhysics]

Thanks for the appreciation dear. Yes, there's a criteria. The adjusted R2 value is supposed to be closed to 1. This value is shown in the data sheet or table after fitting.

[@nicholasalifa6871]

Thank you for your valuable video. Do you have an idea of how to use deconvolution to determine protein structure?

[@SAYPhysics]

Thank you for your comment! While the tutorial focused on the basics of deconvolution in OriginLab, I appreciate your interest in applying it to protein structure analysis. Deconvolution can indeed be a valuable tool in some aspects of structural biology. However, the process of analyzing protein structures is more complex and involves techniques like X-ray crystallography, NMR spectroscopy, and computational modeling. Deconvolution is then performed on these spectra for further deep insight.

Can this be used to get activation energy & kinetic constants? I’m doing TGA for biomass combustion. Please Dr I need your suggestion. Thank you.

[@SAYPhysics]

Yes. Deconvolution is a process in which you isolate all contributing peaks in the composite. Any calculation you can perform, if you're able to identify your peak (s) of interest. Thanks

[@AishwaryaPatil-pc3uo]

this is very helpful, thank you. but in my case the fitting lines are overlapping on the original peaks , what to do?

[@SAYPhysics]

Thanks for the appreciation dear. If your peaks are overlapping the original peaks then its a good sign for a perfect fit.

[@igsr1869]

Thank you, Dr. May I ask a question ? My peaks are sharp. Should I do curve fitting before starting the deconvulotion process?

[@SAYPhysics]

Yes, it is possible to perform deconvolution in OriginLab even if the peaks are very sharp. Deconvolution is a mathematical technique used to enhance the resolution of signals by separating overlapping peaks or removing unwanted contributions from a signal. Thanks

Thank you Dr for another amazing tutorial. I have a question tho, while deconvoluting, I noticed the x values of the cumulative fit are limited to 1000 values only, while my original data has over 2000. So when I try to fit the C fit with my original spectrum, the C fit shape are shrink, thus inable to fit in graph. By any chance, do you know how to resolve this problem? I appreciate your time thank you!

[@SAYPhysics]

Thank you for your kind words and for bringing up this issue. I understand the frustration you're experiencing with the limitation on the number of x values for the cumulative fit in Origin. It seems like your original data has more data points than the cumulative fit allows, resulting in the fit shape shrinking when you attempt to fit it with your spectrum. To address this problem, I'd be happy to take a closer look at your Origin file. Please feel free to send it to me at [e-mail]. Once I receive it, I'll examine the data and see if there's a workaround or solution to ensure that the cumulative fit aligns properly with your original spectrum. Thank you for reaching out, and I appreciate your patience as we work to resolve this issue.

[@ayeshagul8002]

Hello Sir, I am working on the deconvolution of peaks using origin. The problem I faced is during the converging, The width and area of each peaks do not allow the peaks to be properly coverged. How should I select each peak width and area specifically? My second question is how to use the area under the curve for quantification purposes? Thanks

[@SAYPhysics]

When deconvolving peaks using OriginLab or any other software, selecting appropriate peak widths and areas is crucial for proper convergence. Here are some guidelines to consider: Peak Width Selection: Start with an initial estimate of the peak width based on your prior knowledge or assumptions about the system. Adjust the peak width incrementally to achieve the best fit to your experimental data. You can use peak fitting functions like Gaussian, Lorentzian, or Voigt to model the peak shapes. Each function has a width parameter that you can adjust. Peak Area Selection: The area under a peak represents the integrated intensity or quantity of the corresponding component in the sample. The area should be selected in such a way that it accurately reflects the true quantity of the component. The area calculation depends on the peak fitting function used. For example, for a Gaussian peak, the area is proportional to the amplitude (height) multiplied by the square root of 2π times the standard deviation. It is important to ensure that the peak area is not affected by nearby overlapping peaks. In such cases, appropriate baseline corrections or baseline modeling techniques can be employed to separate the peaks and accurately determine their individual areas. Regarding your second question, the area under the curve (AUC) can be used for quantification purposes in several ways: Concentration Determination: If you have a calibration curve relating the analyte concentration to the AUC, you can use the AUC of your sample to estimate its concentration. The calibration curve should be constructed using standards with known concentrations and their corresponding AUCs. Comparative Analysis: The AUC can be used for comparative analysis between samples. By comparing the AUCs of different samples, you can infer the relative quantities or concentrations of the analytes present in those samples. Quality Control: AUC can be used as a quality control parameter to assess the reproducibility of a measurement technique or the stability of a sample over time. By monitoring the AUC of a known standard or control sample, you can determine if the measurement system or sample integrity is consistent. Remember, when using AUC for quantification, it is essential to establish a reliable calibration curve or reference standards to ensure accurate and precise measurements. Further, I'll suggest watching the following tutorials for FWHM. kzbin.info/www/bejne/qqvMiYWMab2AZs0 kzbin.info/www/bejne/Z4vMdX1pg7-hgpo kzbin.info/www/bejne/npnLYpeLoc5qeKs Thanks

sir how to calculate % of beta sheet, turn and random coil from FTIR deconvulated spectra

[@SAYPhysics]

To calculate the percentage of beta sheet, turn, and random coil, you can use specialized software or perform a manual analysis. Popular software tools for this purpose include DICHROWEB, K2D3, and CDSSTR, which can assist in deconvoluting FTIR spectra and estimating secondary structure percentages. If you prefer a manual approach, you may want to use established methods like the Reed and Richards method or others based on curve-fitting algorithms. These methods typically involve assigning specific spectral regions to different secondary structures and fitting the experimental spectra accordingly. Thanks

[@manish2mech]

Thank you for your video. I have seen many tutorials but none of them gives a tutorial on complex spectrums (which has 20-30 peaks). Generally, it is impossible to fit them in a single trial. Can you make a video on it?

[@SAYPhysics]

Thanks for the appreciation. The procedure I have shown has nothing to do with number of peaks (as many as available can be chosen for fitting). If you have some complex peaks, you can share your data file, I can have a look. Thanks

Sir, from 2 weeks I'm stuck for deconvolution, which I want for amide region (in FTIR). As I m confused whether to go for secondary derivative or from smooth one. I saw your baseline correction video too, but with little success. Sir, please gv your precious time to overcome sleepless nights and If you allow may I share my data once.

[@SAYPhysics]

When a noise is such that it's reflected all over the spectrum, you may only go then for the smoothness of the plot. If the deconvolution isn't working on the whole spectrum, try to plot only that region of the plot where you're interested to deconvolute the peaks. Try this, I hope you'll have a peaceful sleep.
