Abstract
A method of operating a differential mobility spectrometer (DMS) includes providing a heater disposed proximate a ceramic body of a DMS cell. A first control voltage is applied to the heater. A first threshold is detected by a first sensor disposed within a curtain plate that substantially surrounds the DMS cell. A second control voltage is applied to the heater based at least in part on the detected first threshold. During application of the second control voltage, a mass spectrometry analysis of a gas within the DMS cell is performed.
