Conventional IMS (ion mobility spectrometer) with linear low field is widely used in portable chemical agent detector. Detector should be quickly, accuracy, high selectivity and high sensitivity. To do this, we may regard the ongoing shift of interest from conventional IMS to FAIMS (Field Asymmetric waveform Ion Mobility Spectrometry). Because FAIMS is one of the powerful portable detectors for chemical agents. Our study is focused on nonlinear effect of ion mobility in high electric field. Because the ion mobility itself control the characteristics of FAIMS device.
We have been developed the experimental set up for the measurement of ion mobility, especially, its variation in high field. First we decided benzene, toluene as a sample and then simple electrodes like FAIMS were constructed. Their ionization part used a dye laser to construct the REMPI system. This can simplify whole measurement system. It can simply define the starting time of sample ions, and what they are. Through the experimental set up, we observed ion mobility of nonlinear region in high field. These results would be established simulation of ion mobility in high field. Then it should be applied to optimized asymmetric waveform of FAIMS. The measurement system of ion mobility for the FAIMS device and their mobility values will be presented.
Key word : Ion mobility, FAIMS, nonlinear region in high field, REMPI
