ESI-IMS-QTOF-MS instrument
ESI-IMS-QTOF-MS instrument. This tandom instrument volatilizes ions with its electrospray ionization source and separates them in accord with their mobility in argon. The structure of each size-resolved ion is then probed with tandem MS/MS mass spectrometry.

Certain commercial materials and equipment are identified on this website in order to adequately specify the experimental protocol. Such identification neither implies recommendation or endorsement by the National Institute of Standards and Technology nor does it imply that the material or equipment identified is the best available for the purpose.
