Deconvolutions and Baseline Subtraction

Before you can obtain peak points for a calibration curve you must correct for background and overlapping peaks. Modern instruments often allow you to do this subtraction on their platform manually. However you may not have that option and need to do the corrections yourself. Additionally if you don’t know what you are doing with the software on the instrument it is garbage in and garbage out (GIGO).

One exercise on this page is to baseline subtract data from a simple Raman spectrometer. The second is deconvolution of two overlapping peaks in a UV-Vis spectra.
