GS8.4 - Measurement of Gas Mixture Using Field Asymmetric Ion Mobility Spectrometry

The performance of Field Asymmetric Ion Mobility Spectrometry (FAIMS) was investigated for the vapor mixtures. We measured the binary mixture composed of ethanol and acetone. The head space above the binary mixture liquid was introduced into FAIMS. Although the fingerprint originating from ethanol was not initially observed, it gradually appeared as time increased. It suggests that there is a possibility to obtain the feature of the mixture composition.
