A planar tandem differential mobility spectrometer was integrated with a middle reactive stage to fragment ions which were mobility selected in a first analyzer stage using characteristic compensation and separation fields. Fragmentation occurred in air at ambient pressure of 660 Torr (8.8 kPa) with elec. fields of 10 to 35 kV cm-1 (E/N of 52 to 180 Td) between two 1 mm wide metal strips, located on each analyzer plate between the first and second mobility stages. Field induced fragmentation (FIF) spectra were produced by characterizing, in a last stage, the mobilities of fragment ions from protonated monomers of 43 oxygen-containing volatile organic compounds from five chem. classes. The extent of fragmentation was proportional to E/N with alcs., aldehydes, and ethers undergoing multiples steps of fragmentation; acetates fragmented only to a single ion, protonated acetic acid. In contrast, fragmentation of ketones occurred only for Me i-Bu ketone and 2-hexanone. Fragment ion identities were supported by mass-anal. and known fragmentation routes and suggested that field induced fragmentation at ambient pressure can introduce structural information into FIF spectra, establishing a foundation for chem. identification using mobility methods. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Related Products of 112-14-1).
Octyl acetate (cas: 112-14-1) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Related Products of 112-14-1
