Ion-selective ppb-level gas sensor
|Förderung durch:||This research is founded by the German Research Foundation(DFG)|
The objective of this work is the development of a fast ion-selective ppb-level gas sensor based on pulsed atmospheric pressure chemical ionization and ion-ion-recombination kinetics. The major tasks are the characterization of the ion generation and ion-ion-recombination kinetics of gas mixtures with various analytes and concentrations. Further, the measurement data should be analyzed by appropriate pattern recognition algorithm.
