Abstract (en)

[origin: WO2006046077A1] An ion mobility spectrometer is described having an ion filter in the form of multiple parallel ion channels defined by conductive layers (6, 8) separated by non-conductive layers (7, 9). A time-varying electric potential applied to the conductive layers allows the filter to selectively admit ion species. The device may be used without a drift gas flow. Microfabrication techniques are described for producing microscale spectrometers, as are various uses of the spectrometer.
