Did you know?

WebFlow tube techniques (flowing afterglow, selected ion flow tube) have been used extensively to study ion–molecule reactions and to measure their rate coefficients. There are far fewer studies on the thermal decomposition of gaseous ions. Recently, cluster ions and noncovalent complexes have, however, received considerable attention. ... A flowing afterglow is an ion source that is used to create ions in a flow of inert gas, typically helium or argon. Flowing afterglow ion sources usually consist of a dielectric discharge that gases are channeled through to be excited and thus made into plasma. Flowing afterglow ion sources can be coupled with a selected-ion flow-tube for selection of reactant ions. When this ion source is coupled with mass spectrometry it is referred to as flowing afterglow mass spectrometry.
