Abstract

Cylindrical ion traps (CITs) that can be used for molecular sample identification, as well as systems and methods using the same, are provided. A CIT can utilize a notched ring electrode having an inner diameter that increases as a first end of the CIT is approached from the center of the CIT or from a second end of the CIT. The first end can be the one positioned closer to the ion detector than is the second end, which can be positioned closer to the ion source than is the first end.
