The Agilent IM-QTOF LC/MS system is a major advance in the commercial development of analytical ion mobility‑mass spectrometry. Optimized development of a uniform drift field mobility cell and interface to a high resolution Q-TOF instrument gives a significant gain in ion mobility performance. The use of ion funnel technology pioneered by Agilent for both triple quadrupole and Q-TOF instruments over the past three years has been incorporated into the new IM-QTOF system. This has resulted in combined ion mobility separation and mass resolution with high sensitivity.

Recent work with several collaborators has confirmed that the instrument delivers:

• Greater separation of lipids and glycopeptides

• More accurate collision cross section measurements enabling more confident characterization of structural conformations and isomeric compounds 

• Greater numbers of trace level peptides in complex matrices 

• Preservation of structural fidelity of metallo-proteins in liquid phase solutions
