Experiment and Simulation Study of Automatic Temperature Control FAIMS Chip.

The temperature of the carrier gas will affect the performance of high-field asymmetric ion waveform mobility spectrometry (FAIMS), changing the height and position of the peaks of the FAIMS spectrum. In this study, we explored the influence of temperature on the FAIMS spectrum through experiment and simulation. In the experiment, the PCB self-heating temperature control FAIMS system was used to study the effects of temperature changes on the FAIMS spectra of ethanol, acetic acid, acetone, and ethyl acetate, and the coefficient solving methods of mobility and were derived in detail.
