In this device, the fixed mechanical positioning and conductive\u2010contact connection help restore consistent electrode positioning. Theoretical analysis and SIMION simulations were first performed to predict the influence of plate spacing, followed by experimental validation. Plate spacings of 0.3, 0.4, 0.5, and 0.6\u2009mm were set, and acetone samples were detected under the same electric field conditions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The simulation and experimental results show that with the increase of plate spacing, the FAIMS signal intensity (peak height) increases significantly: when the plate spacing increases from 0.3 to 0.6\u2009mm, the signal intensity of the main peak increases by approximately 100%, and that of the secondary peak increases 4.6\u2010fold. Moreover, the relative standard deviation (RSD) of all spacings is below 5%. Increasing the plate spacing significantly improves the sensitivity of the FAIMS system while the resolution does not change significantly, and the system maintains good separation capability.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study provides a
