SUMMARY

The discussion focuses on using Seasolve's PeakFit software for fitting Gaussian curves to UV-vis spectra. The user seeks advice on automating the peak fitting process to achieve a specific R-squared value, as their current method feels improvised. Another participant suggests exploring the free alternative, Fityk, for peak fitting tasks. The conversation highlights the need for effective techniques in spectral analysis using PeakFit.

PREREQUISITES
  • Understanding of UV-vis spectroscopy
  • Familiarity with Seasolve's PeakFit software
  • Knowledge of Gaussian curve fitting techniques
  • Basic statistical concepts, particularly R-squared values
NEXT STEPS
  • Research automated peak fitting techniques in Seasolve's PeakFit
  • Explore the features and capabilities of Fityk for peak fitting
  • Study statistical methods for determining R-squared values in curve fitting
  • Learn about best practices for analyzing UV-vis spectra
USEFUL FOR

Researchers, chemists, and data analysts involved in spectral analysis and curve fitting, particularly those using Seasolve's PeakFit or seeking alternatives like Fityk.

Now, I am not sure if this is the appropriate forum to post this in but I need some help with a particular peakfitting software, and my advisor has never used it before so I can't really ask anyone in our lab.

I am currently using seasolve's PeakFit, what I am trying to do is fit a gaussian curve to some UV-vis spectra in a particular wavelength range. I can do this but the way I am doing this seems very ad hocish to me. What I really want to do is use the automated peakfiting to fit a gaussian to this particular wavelength range to a particular r-squared value. I am wondering if anyone has any advice for doing this, or tips and tricks for using peakfit in general.

Thanks in advance for any replies.

I haven't used PeakFit for a long time, so don't have an answer to your question, but you may have a look at another peak fitting program: http://www.unipress.waw.pl/fityk/" (it's free).
