Abstract
An atmospheric ion mobility spectrometer including a spectrometer tube having a shutter grid defining a reaction region and a drift chamber. The tube includes an inlet at the end of the drift chamber opposite the shutter grid in communication with ambient air that allows the air to be introduced into the tube. The air acts as the sample, carrier gas and drift gases within the IMS.
