Abstract
Ion mobility spectrometers are uniquely sensitive chemical detectors used in a variety of application spaces. Chemical dopants are commonly used with these instruments to improve sensitive and selectivity of detected species. A dopant source with a wicking filament approach to control emission of a chemical dopant in a small format is disclosed herein. This is demonstrated for several dopants used with IMS detectors and initial performance parameters (e.g., emission rate, emission lifetime, emission concentration control) have been investigated. The dopant source can be used in other chemical ionization systems.
