What’s the big deal about ion mobility mass spectrometry?

Ion mobility spectrometry (IMS) is a technique that differentiates ions based on their size, shape, charge, and mass. While often used in small, portable devices at airports and remote locations for rapidly detecting small molecules whose mobility is known (for example, certain narcotics and explosives) when coupled with liquid chromatography-mass spectrometry (LC/MS), IMS provides an…
