Differential mobility spectrometry (DMS) and ion mobility spectrometry are analytical techniques used to separate hard to resolve ions based on their gas phase mobility. Multiple types of ion mobility devices exist, such as drift tubes, traveling wave, and high-field asymmetric waveform devices. However, none carry the power of SCIEX SelexION® technology that delivers highly-selective, robust and powerful ion separation that significantly enhances your quantitative and qualitative performance.

For scientists who are challenged by assays with isobaric interferences and difficult-to-separate co-eluting contaminants, this fast, reproducible and easy-to-use approach will enhance the selectivity of your LC-MS/MS separations.
Enhance selectivity without the need for additional complex sample preparation
Perform fast separation analyses compatible with UHPLC timescales
Overcome co-eluting matrix interferences and improve data quality in complex samples
Separate and quantify isobaric molecular species for more accurate biological insights
Maximize mass spec workflow flexibility with easy install that doesn’t require breaking the system vacuum
SCIEX SelexION device is a small, planar mobility cell that significantly increases analytical separation power, even if compounds have identical molecular weights and chromatographic retention times, made possible by a mobility region and optional polar modifiers in the transport region.
Two parallel flat plates define a mobility region, allowing nitrogen carrier gas to create forward directional flow between the ion source and the mass spec analyzer. Analytes are separated based on their respective size, shape, charge state and chemical interaction, prior to entering the mass spec.
Polar modifiers in the transport region can lead to a significant increase in analyte separation and peak capacity. Chemical modifiers, such as isopropanol or acetonitrile, influence ion mobility based on their ability to cluster with analytes.
See how the small, planar SelexION DMS device can enhance analytical separations for isobaric species and co-eluting contaminants.
SelexION offers a unique approach to separation that is unmatched by any other available method. Firstly, it is a planar device that separates ions based on differences in mobility in two different regions of the field dependent mobility curve (Ref 1). Secondly, due to its size, the system can operate with very short residence times with optimal performance when using chemical modifiers, and can be used in transparent mode to allow for maximal workflow flexibility.
SelexION offers the ability to turn off separation voltage and operate in a ‘transparent’ mode to transmit all ions, providing the option to perform non-ion mobility assays without removing the front-end device (Ref 1).
Used in pharmaceutical, academic and food and environment testing labs across the globe, SelexION DMS technology brings the power of ion mobility to even routine users. The technology is compatible with several SCIEX Triple Quad™, QTRAP® and TripleTOF® platforms. Explore the table below to see what SelexION device is right for your system.
SelexION+ ion mobility cell is also available for use on SCIEX 6500+ Series mass spectrometers. The SelexION+ device is enhanced by a jet injector that reduces the ion residence time within fringing fields at the DMS inlet. This delivers a 2-fold increase in transmission over the standard SelexION device.
From pharmaceutical drug discovery/development and lipidomic analysis to food, environmental testing and so much more, learn how SelexION technology has enhanced results in these key applications.
SelexION Differential Ion Mobility Technology takes some of the world's most advanced mass spectrometry systems and adds a new dimension of selectivity to enhance quantitative and qualitative performance. Compatible with many SCIEX systems, SelexION device can be installed and uninstalled within 2-minutes without breaking vacuum, giving you the freedom to use ion mobility technology as needed.
