Applications of Advanced Multichannel Laser Raman Spectroscopy to Problems in Marine Chemistry
Abstract
Laser Raman multichannel spectrometry, and Fourier Transform (FT)- Raman techniques were evaluated and applied to the analysis of low levels of inorganic nutrients in seawater. The best results were obtained in analyzing nitrite in seawater with an azo-dye scattering (SERS) with resonance Raman scattering (RRS), i/e., SERRS, technique using silver colloids. The limit of detection of the azo-dye complex of nitrite with visible laser excitation and the SERRS technique is estimated to be 1 nm in basic seawater solutions and 12 nm in the acidic solutions.
