摘要
A system with Li(+) ion attachment (IA) ionization has been developed for the direct detection of intermediates formed in burning flames by mass spectrometry. Dimethyl ether (DME) among alternative fuels was selected as a test substance to examine the capability of the system. As a result, intermediates generated in a premixed DME-air flame were directly detectable as Li(+) adduct ions. By moving the burner on an X-Y stage, spatial distribution profiles of different species, including unburned DIME and formaldehyde, were obtained for three types of flames: diffusion, partially premixed, and premixed.
