The Coulomb repulsion accounting procedure integrated on portable IMS

Abstract

Ion Mobility Spectrometry (IMS) is a traditional analytical method for the detection of explosives, drugs and toxic industrial compounds [1-4]. Today IMS research activity in the world focuses on medical topics, the task of noninvasive medical diagnostics of diseases by substances-biomarkers contained in the exhaled air [4].The method has such advantages as high sensitivity, compact construction and low cost. Ion Mobility Spectrometry method based on measuring of ion mobility in the constant electric field in the presence of atmosphere. Coulomb's repulsion is an important effect of Ion Mobility Spectrometry data distortion.
