Abstract
Ion mobility spectrometers and methods for determining the ion mobility of a sample gas in dry air as drift gas are disclosed. The ion mobility spectrometers comprise a drift chamber, a reaction chamber, a dielectric barrier discharge ionisation source, a control unit, and a DBDI source, a pressure sensor, and a temperature sensor arranged in the chamber. A light source irradiates the DBDI source with light in a wavelength range from about 240 nm to about 480 nm. The control unit is designed to set an ignition voltage of the DBDI source and to control the light source depending on a determined pressure value and a determined temperature value. The methods control and utilize the control unit for operating the ion mobility spectrometer.
