Trace gas concentration in art ms traps |
| abstract |
A method for detecting specific gas species in an ion trap, which is a minor component of a first low concentration in the gas volume, comprises ionizing a gas containing the specific gas species, thereby producing specific ion species. The method further comprises producing an electrostatic potential in which the specific ion species are constrained to trajectories in the ion trap. The method includes the steps of exciting specific ion species confined by an AC excitation source having an excitation frequency, scanning the excitation frequency of an AC excitation source to release specific ion species from the ion trap, Gt; The method further comprises increasing the concentration of specific ion species in the ion trap for a first lower concentration before scanning the excitation frequency that emits ions of the particular gas species. |
