Figure 1

shows three FAIMS models in which the micro-fabricated FAIMS geometry in the model “a”, “b” and “c” are identical (L =15 mm and g = 0.5 mm). The models defer in the detector assembly. In model “a” single vertical detector electrode is placed at 14.99 mm; in model “b” two parallel electrodes (L = 5 mm) separated by 0.5 mm were placed 5 mm away from the FAIMS electrodes; in model 3 the detector electrodes were replaced by a capillary (L = 60 mm and i.d = 0.5 mm) 0.5 mm away from the FAIMS electrodes.
