Abstract
A sample is ionized by chemical ionization by flowing the sample and a reagent gas into an ion source at a pressure below 0.1 Torr. While maintaining the ion source at a pressure below 0.1 Torr, the reagent gas is ionized in the ion source by electron ionization to produce reagent ions. The sample is reacted with the reagent ions at a pressure below 0.1 Torr to produce product ions of the sample. The product ions are transmitted into an ion trap for mass analysis.
