Earl W. McDaniel has been called the father of ion mobility mass spectrometry. In the early 1960s, he coupled a low-field ion mobility drift cell to a sector mass spectrometer. The combination of time-of-flight mass spectrometry and ion mobility spectrometry was pioneered in 1963 at Bell Labs. In 1963 McAfee and Edelson published an IMS-TOF combination. In 1967 McKnight, McAfee and Sipler published an IMS-TOF combination. Their instrument included an o… WebA conventional ion mobility spectrometer consists of the reaction region, including the ion source and ion gate, and the drift region and detector.
