Reduction of Background Fluorescence from Impurities in Protein Samples for Raman Spectroscopy

Figure 6

Initial spectrum of BSA and after 30 and 60 min of exposure to external 635 nm laser and 532 nm laser and to 633 nm Thermo Fisher Raman spectrometer laser. All the spectra were measured with 1 s exposure and accumulated 10 times. The spectra were expressed relative to the initial values.
