Dosage des carotenoides de la macrofaune benthique par spectrometrie d'adsorption visible
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Merlin, J; Noel, Philippe; Lafageoe-szydlowski, S; Petitt-cossi, G; Wallart, F.
The resonance Raman spectrometry allows the determination carotenoid composition. This method has many advantages in particular to analyse a non-purified solution without measuring the other constituents. The application of this technique is used for benthic macrofauna studies.

Study of inorganic ammonium compounds in individual marine aerosol particles by laser microprobe mass spectrometry
Provedor de dados: Open Marine Archive
Autores: Otten, P.; Bruynseels, F.; Van Grieken, R.
Ammonia is important in the atmosphere because it neutralizes acidic species. The relative importance of different inorganic ammonium compounds (chloride, nitrate and sulfate) in marine air chemistry was studied by single-particle characterization with the laser microprobe mass analyser. Standard aerosols were generated as a reference for compound identification, based on the fingerprint spectra obtained, and calculation of the relative sensitivity achieved for different ions in a marine aerosol matrix. The relative sensitivity for ammonium was low. Aerosol samples were collected in the Southern Bight of the North Sea under different meteorological conditions and examined for their ammonium compounds. Samples collected during an inversion period with...
