Varian CP-4900 MicroGC, four channel, with differential mobility detector (first from the right)

A differential mobility detector (DMD) is a type of microelectromechanical system, radio frequency modulated ion mobility spectrometry (MEMS RF-IMS) device.[1]

Portable devices

Though its small in size, it easily fits into portable units, such as transferable gas chromatographs or drug/explosives sensors. For instance, it was incorporated by Varian in its CP-4900 DMD MicroGC, and by Thermo Fisher in its EGIS Defender system, designed to detect narcotics and explosives in transportation or other security applications.
