FAIMS Ion Filter

Field Asymmetric Ion Mobility Spectrometry (FAIMS) • Detects multiple gases simultaneously in under a second • Detection levels below part per billion (ppb) • Sensor can be reprogrammed to detect new gases through software, even after deployment. Hardware stays the same. • 2D chemical signature reduces false alarms The sensor acts as a programmable filter, which separates and identifies chemicals according to their characteristic mobility. The sensor filters out chemicals that don’t have the correct mobility fingerprint. Only the chemicals of interest pass through. The chemicals of interest are then analyzed using software to determine their type and quantity.
