Abstract:
Ion modification An ion mobility spectrometer ( 100 ) comprising a sample inlet ( 108 ) comprising an aperture arranged to allow a sample of gaseous fluid to flow from an ambient pressure region to a low pressure region of the ion mobility spectrometer to be ionised; a controller ( 200 ) arranged to control gas pressure in the low pressure region to be lower than ambient pressure; and an ion modifier ( 126, 127, 202 ) configured to modify ions in the low pressure region, wherein the ions are obtained from the sample of gas.

Claim (Index 6):
An ion mobility spectrometer comprising:\n a sample inlet comprising a membrane inlet arranged to allow a sample of gaseous fluid to pass from an ambient pressure region to a low pressure region of the ion mobility spectrometer to be ionised; an ioniser disposed in the low pressure region of the ion mobility spectrometer and configured to ionise the sample; an ion modifier configured to modify ions in the low pressure region, wherein the ions are obtained from the sample of gaseous fluid, wherein the ion modifier comprises two electrodes spaced apart in the direction of movement of the ions towards the detector; a controller arranged to control gas pressure in the low pressure region to be lower than ambient pressure by at least 200 mb, wherein the controller is configured to control the ion modifier in a first mode to subject ions to an alternating electric field to modify the ions as they pass through the ion modifier, and to control the ion modifier in a second mode to allow ions to pass through the ion modifier; and and an ion modifier configured to modify ions in the low pressure region, wherein the ions are obtained from the sample of gas a detector configured to measure a time of flight associated with the ions travelling from the ioniser, wherein the detector is configured to provide a signal to the controller indicating arrival of ions.
