Source assembly for chemical ionization

Exhibit no. 698

Chemical ionization is a technique based on the reaction of a neutral with an ion in the gas phase. 

A reagent gas like methane, ammonia or isobutene is introduced to the ion source similar to the electron ionization source. Electrons ionize the reagent gas and the reagent ions formed in this way interact with neutrals.
The picture shows the chemical ionization source used in a quadrupole mass spectrometer MD 800 manufactured by Fisons Plc. in 1992.
