Raman spectra tend to have thermal backgrounds or fluorescence, and these characteristics can adversely affect matching when performing spectral library searches. They may also lead to a degradation in accuracy when determining components as part of quantitative analysis. ®-based Raman environment) software from Renishaw features a patented Intelligent Fitting baseline subtraction tool that can be used to automatically and accurately eliminate unwanted backgrounds from spectra. Using Intelligent Fitting offers accurate, consistent results because there is no longer any need for manual baseline removal, which is often subjective and time-consuming. Using Intelligent Fitting, it is possible to remove both simple and complex baselines from a single spectrum. This can also be done automatically from many spectra in a Raman map.
