Dimethyl ether (DME) is a useful reagent gas for the characterization of a variety of diverse biologically important or environmentally signiรcant classes of compounds. In this work the gas-phase ion-molecule reactions of DME with 23 a-amino acids were investigated and the collision-induced dissocia
## Abstract Dimethyl ether (DME) chemical ionization mass spectrometry of a number of polynuclear aromatic hydrocarbons (PAHs) gave rise to a variety of fragmentโmolecule adduct ions resulting from ionโmolecule reactions with the reagent gas. In 18 out of 22 cases, it was possible to differentiate
## Abstract Dimethyl ether (DME) chemical ionization mass spectrometry with introduction by direct exposure desorption was utilized for the characterization of a variety of nitramines, nitroaromatics and related compounds. For the nitramines and for many of the nitroaromatics the most abundant ions
