Fit multiple peaks on a FTIR spectrum data

[#1]

Hi all, 

I would like to know if it was possible to fit multiple peaks (a lot, more than 10) from a FTIR spectra using JMP? I have read some things about using the modelling "Fit Curve"or "Fit non-linear" but it tries to fit one single curve for the entire set of data instead of individual peaks. 

Thanks,

Louis

Hi @LGaspard_98,

Welcome in the Community !

For the analysis of spectral data, I would recommend trying the Functional Data Explorer. This platform comes with many interesting modeling options (Wavelets models, Multivariate Curve Resolution, Peak Finder, ...) for spectral data.

There are some ressources that can help you using this platform and give you some ideas for modeling :

I hope this answer will help you,

Hi @LGaspard_98 ,

As Victor mentioned, we have a lot of valuable tools available in the Functional Data Explorer tool to pick and model peaks, we can also perform multivariate modelling, with techniques like Partial Least Squares that can work well to create a predictive model of multidimensional spectra data.

Here is a great guide on spectral analysis in JMP: https://www.jmp.com/en_gb/articles/analyzing-spectral-data-modeling-options.html 

Do you have an example of what you're trying to achieve? An example dataset?
