Observed enrichments of NaNO3 in marine aerosols have been attributed to NaNO3-formation during the sampling procedure in the case of filter sampling. This artifact was investigated for cascade impactor sampling. Experiments were carried out in which

Laser Microprobe Mass Spectrometry (LAMMA) is used to examine micrometric particles of calcium oxyanion salts (CaCO 3 , CaSO 4 , CaSO 4 ·2H 2 O) and calcium oxide, in both the positive and negative ion mode. The major molecular ions, appearing in th

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 wi

Laser microprobe mass analysis spectra of micrometric particles of Na/sub 2/SO/sub 4/, Na/sub 2/SO/sub 3/, and Na/sub 2/S/sub 2/O/sub 3/ have been studied. The negative ion mode spectra are dominated by SO/sub n//sup -/ ions; their pattern with respe

Bilayers of carbon, consisting of a layer of natural carbon and a second layer highly enriched in 13 C, were investigated with the LAMMA 500- ® instrument. When such a bilayer is perforated by the laser beam, comparable amounts of 12 C and 13 C are
