Raman spectroscopy is often considered a nondestructive analytical technique; however, this is not always the case. The 300-mW 785-nm near-infrared (NIR) laser source used with many commercially available instruments has sufficient power to burn samp

Raman spectroscopy (785 nm excitation) was used to determine the overall carotenoid (astaxanthin and cantaxanthin) and fat content in 49 samples of ground muscle tissue from farmed Atlantic salmon ( Salmo salar L.). Chemically determined contents ran

Luminescence and Raman measurements of metal (Er3+, Tb3+, Sm3+, Eu3+, UO22+, and Na+) nitrates from multiple spectral windows are combined and analyzed to determine whether this multispectral approach provides any benefit over the best single-measure

The potential of Raman spectroscopy to discriminate between architectural finishes (household paint) has been investigated using a test set of 51 “lilac” paints and three different excitation wavelengths. The spectra obtained with visible excitat
