High resolution ion mobility
WebIon mobility interfaced with mass spectrometry (IM-MS) has become an important technique for the analysis of complex biological samples. (1−6) Similar to chromatography, the added structurally selective separation capabilities of IM improve analyte coverage and aid in the discrimination of isomeric and isobaric species that otherwise hinder … WebApr 1, 2016 · Ion mobility spectrometry (IMS) is a well-established technique for fast trace gas detection, offering limits of detection in the low ppt v -range for measuring times of less than a second. The sensing principle of IMS is based on a separation of ions by their ion-specific mobility in a drift gas under the influence of an electric field [1].
