Abstract:
1. A method of operating a smart FAIMS sensor comprising: providing a FAIMS sensor comprising a filter for separating ionic species, the filter having at least two electrodes, each of the at least two electrodes having first and second contact pads separated by a high resistivity material, drive signals controlled by a controller being applied between the first and second contact pads and defining an operating point of the sensor, and a detector for collecting separated ionic species, the detector generating a detection signal in response to the collected ionic species; setting the operating point of the sensor to a first operating point; generating a first detection signal while the sensor is operating at the first operating point; setting the operating point of the sensor to a second operating point based on the first detection signal; and generating a second detection signal while the sensor is operating at the second operating point.
