Role of Nitrogen Oxides in Ozone Toxicity

The preparation of ozone/nitrogen oxides mixtures in air containing the nitrate radical, their reaction with the unsaturated lipid 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC), and the determination of the reaction products in comparison to those obtained from a reaction with only ozone in air by MALDI-FTMS is described. The results indicate the importance of nitrate radical in ozone toxicity

FTMS of Natural Polymers

The ability of Fourier-transform mass spectrometry to produce spectra of some natural polymers - peptides, lignin and humic acid - that include stable, high-mass ions formed by laser desorption/ ionization (LDI) and matrix assisted laser desorption/ionization (MALDI) is demonstrated
