Lignin Quantitation by Ft-raman Spectroscopy
Because of the structural complexity of biomass, quantitation of lignin in a variety of wood and plant cell walls is difficult. Consequently, to measure lignin in different plant species, a number of different methods exist. The methods can give different values for the same material samples and such differences result from the nature of the biomass. In the past, although there have been many a...
متن کاملApplications of Ft Raman Spectroscopy for the Characterization of Cellulose
FT Raman spectroscopy was used for the investigation of cellulose and cellulose derivates. Lattice structures of cellulose, polymorphic modifications I and II, as well as amorphous structure were clearly identified by means of FT Raman vibrational spectra. Chemometric models were developed utilizing univariate calibration as well as methods of multivariate data analyses of the FT Raman spectral...
متن کاملCharacterization of Chrysotile, Antigorite and Lizardite by Ft-raman Spectroscopy
We analyzed samples of antigorite, lizardite and fibrous chrysotile, three representative minerals of the serpentine group, to determine their chemical and structural properties, and their FT-Raman spectra. The low-frequency region of the spectrum (1200– 200 cm–1), which corresponds to the lattice-vibration modes, was then analyzed, and the observed bands attributed, on the basis of our results...
متن کاملClassification of frankfurters by FT-Raman spectroscopy and chemometric methods.
Frankfurters are widely consumed all over the world, and the production requires a wide range of meat and non-meat ingredients. Due to these characteristics, frankfurters are products that can be easily adulterated with lower value meats, and the presence of undeclared species. Adulterations are often still difficult to detect, due the fact that the adulterant components are usually very simila...
متن کاملBiochemical analysis of human breast tissues using FT-Raman spectroscopy
In this work we employ the Fourier Transform Raman Spectroscopy to study normal and tumoral human breast tissues, including several subtypes of cancers. We analyzed 194 Raman spectra from breast tissues that were separated into 9 groups according to their corresponding histopathological diagnosis. The assignment of the relevant Raman bands enabled us to connect the several kinds of breast tissu...
