Definition
Ion mobility spectrometry is an analytical technique that separates ions based on their mobilities through an electric field in a non-ionic medium. Ion mobility spectrometry separates compounds based on the differences in mobilities, which depends on the size and charge of the ion, electric field, and interaction between the ions and the medium.
Ion mobility spectrometry is an established method of choice for the detection of explosives and illicit drugs. Commercial ion mobility spectrometers are available and are widely employed in public areas.
Overview
In an ion mobility spectrometer analyte ions are moved by an applied electric field along a tube, where the ions experience multiple collisions with neutral drift gas molecules. Ion mobility spectrometry offers milliseconds-fast analysis time,...
