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, … Meer weergeven 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 … Meer weergeven 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 ease of use, relatively high sensitivity, and highly compact design have … Meer weergeven The molecules of the sample need to be ionized, usually by corona discharge, atmospheric pressure photoionization (APPI), electrospray ionization (ESI), or radioactive atmospheric-pressure chemical ionization (R-APCI) source, e.g. a small piece of Meer weergeven 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 … Meer weergeven IMS was first developed primarily by Earl W. McDaniel of Georgia Institute of Technology in the 1950s and 1960s when he used drift … Meer weergeven The physical quantity ion mobility K is defined as the proportionality factor between an ion's drift velocity vd in a gas and an … Meer weergeven Ion mobility spectrometers exist based on various principles, optimized for different applications. A review from 2014 lists eight different ion mobility spectrometry concepts. Drift tube ion mobility spectrometry Drift tube … Meer weergeven WebIon mobility spectrometry (IMS) is widely used for national security and law enforcement, placed at key transportation checkpoints such as airports and border crossings for the trace detection of drugs and explosives.
