Ion mobility test
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 … Meer weergeven The molecules of the sample need to be ionized, usually by corona discharge, atmospheric pressure photoionization (APPI), Meer weergeven The drift gas composition is an important parameter for the IMS instrument design and resolution.
