Ion mobility mass spectrometry is a rather recently popularized gas phase ion analysis technique. As such there is not a large software offering to display and analyze ion mobility mass spectrometric data, apart from the software packages that are shipped along with the instruments. ProteoWizard, OpenMS, … See more Ion mobility spectrometry (IMS) It is a method of conducting analytical research that separates and identifies ionized molecules present in the gas phase based on the mobility of the molecules in a carrier buffer gas. … See more Perhaps ion mobility spectrometry's greatest strength is the speed at which separations occur—typically on the order of tens of milliseconds. This feature combined with its … See more The molecules of the sample need to be ionized, usually by corona discharge, atmospheric pressure photoionization (APPI), See more The drift gas composition is an important parameter for the IMS instrument design and resolution. Often, different drift gas compositions can allow for the separation of otherwise overlapping peaks. Elevated gas temperature assists in removing ion clusters that may … See more IMS was first developed primarily by Earl W. McDaniel of Georgia Institute of Technology in the 1950s and 1960s when he used drift cells with low applied electric fields to study gas phase ion mobilities and reactions. In the following decades, he integrated the … See more The physical quantity ion mobility K is defined as the proportionality factor between an ion's drift velocity vd in a gas and an electric field of strength E.
