Determination of the Sensitivity of an External Source Ion Trap Tandem Mass Spectrometer Using Dimethyl Ether Chemical Ionization

Tandem mass spectrometry is a rapid and powerful analytical technique that can provide trace mixture analysis and structure elucidation. The ion trap mass spectrometer has been widely used since it became commercially available in 1983. The reason is attributed to its tandem mass capability.

Within the last decade, a number of studies of ion-molecule reactions of dimethyl ether (DME) ions in the ion trap mass spectrometer have been published by Brodbelt and co-workers. 1,2 Two main reagent ions, of m/z 45 CH 3 O CH 2 C and 47 CH 3 OHCH 3 C , are generated when dimethyl ether is applied as a chemical ionization (CI) reagent gas. 1 According to Colorado and Brodbelt, 3 when DME reacts with compounds possessing
