Mass Spectrometry at Johns Hopkins University Chemistry Department

The JHU Chemistry Department Mass Spectrometry Facility (MSF) is a component of the Chemistry Department's core instrumentation service. It offers a comprehensive range of organic and bio-organic mass spectral techniques to chemical researchers using a suite of instruments equipped with a range of different ionization methods, including EI, CI, FAB, ESI and MALDI. The facility's primary role is to support chemical research conducted within the department, but it is also available for use by researchers from other JHU departments and divisions, along with those from external institutions and commercial organizations. Most instruments are normally operated by users themselves on a "self-service" basis following user training by the facility manager, though a few are operated by our facility manager on a "submitted-sample" service basis. The facility is managed by Dr Phil Mortimer and is located in the basement of Remsen Hall on the University's Homewood Campus. We welcome enquiries from potential users or those wishing to know more about mass spectrometry, it's capabilities and applications. Some information is to be found on these web-pages, but we encourage you to contact us directly or visit us to discuss your questions in detail. We can be reached at :
