Abstract
Abstract In this work, we report the detection in air of two families of illicit drugs using a high sensitivity portable instrument based on a Field Asymmetric Ion Mobility Spectrometry microchip sensor. Methamphetamine, Amphetamine and Δ 9 -Tetrahydrocannabinol (Δ 9 -THC) were detected in the vapor phase at atmospheric pressure and a concentration of 12.5, 25 and 65 ppb, respectively. Each target molecule appears at a specific Compensation Voltage (CV) under a fixed Dispersion Field (DF). A linear FAIMS response at different concentrations and low limits of detection were successfully achieved.
