Ion filter for FAIMS fabricated using the LIGA technique. The ion filter is manufactured using a metal layer to form the ion channels and an insulating support layer to hold the structure rigidly together after separation of the metal layer into two electrodes.

Field asymmetric ion mobility spectrometry filter

Particle detection and characterizing apparatus has an insulating tube along which the particles flow. Five electrodes spaced along the outside of the tube are connected via amplifiers to a processor arranged to measure the charge on the particles. The apparatus also includes a laser and photomultiplier tube arranged to measure the size of the particles so that the nature of the particles can be characterized from their electrical charge and size.
