Abstract
An example ion mobility spectrometry system includes a drift chamber, an ion detector, a thermal sensor, and processing circuitry. The drift chamber is configured to receive an ionized sample and an ionized calibrant. The ion detector is configured to generate a drift signal in response to detecting drifted ions at a predetermined position along the drift chamber. The thermal sensor is configured to generate a temperature signal indicative of a temperature of the drift chamber. The processing circuitry is configured to determine, based on the temperature signal, a mobility relation for a target species; determine, based on the drift signal, calibrant and sample drift times; determine, based on the mobility relation and the calibrant drift time, a target drift time; and detect the target species in the ionized sample by comparing the sample drift time with the target drift time.
