Spectrum Resolution High vs. Low in Gasoline
A spectrum of unleaded premium gasoline obtained with 2 wavenumber resolution compared with a gasoline spectrum obtained with 30 wavenumber resolution. The individual components are easily distinquishable with 2 wavenumber resolution are washed out at 30 wavenumber resolution
Near-IR Absorbance Spectra: Five Unleaded Gasolines
Five near-IR absorbance spectra of different unleaded gasolines. The change in the spectra are very small requiring chemometrics to pull the differences out of the data.
