Abstract:High-field asymmetric ion mobility spectrometry (FAIMS) spectra of single chemicals are easy to interpret but identifying specific chemicals within complex mixtures is difficult. This paper demonstrates that the FAIMS system can detect specific chemicals in complex mixtures. A homemade FAIMS system is used to analyze pure ethanol, ethyl acetate, acetone, 4-methyl-2-pentanone, butanone, and their mixtures in order to create datasets. An EfficientNetV2 discriminant model was constructed, and a blind test set was… Show more
“…Machine learningassisted differentiation of DMS data has been studied for differentiating chemicals from food, 24,25 controlled chemical sources, 17 and diagnosing diseases. [12][13][14] In a pioneering work, Li et al 26 adopted deep learning to identify specic substances in the DMS spectra and reported excellent accuracy.…”
