Determination of Mass Transport Properties in Food/Packaging Systems by Local Measurement with Raman Microspectroscopy
A fast, nondestructive method based on the determination of local concentration profiles in the polymer thickness with Raman microspectroscopy is presented here. It was used to assess the diffusivity of a model molecule (p-terphenyl) in amorphous polystyrene films at 95 C (2.386 1.083 10 m/s). This methodology was validated by comparison with a more classical destructive approach based on the m...

Relative concentrations of Streptococcus mutans and Streptococcus sanguis are important parameters in the study of dental caries, but current methods of measuring these concentrations are time consuming and prone to inaccuracies. We investigate the use of Raman spectroscopy for measuring relative concentrations of these two bacterial species in solid mixtures. To our knowledge, this is the firs...
متن کاملLocal variation in absolute water content of human and rabbit eye lenses measured by Raman microspectroscopy.
Raman spectra were obtained from fresh, fixed and sliced rabbit lenses and from human lens slices. For all lenses and lens slices the ratio R, defined as the Raman intensity at 3390 cm-1 divided by the Raman intensity at 2935 cm-1, was measured at different locations along the visual and equatorial axis. The ratios R were transformed to absolute water mass percentages by measuring solutions wit...
