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 mass spectral analysis techniques to researchers using four different instruments equipped with a range of different ionization methods, including EI, CI, FAB, ESI and MALDI. The facility’s primary purpose is to support research conducted within the Chemistry department, but the services are also available to researchers from other JHU departments and divisions, as well as to external users on a limited basis. Three of the instruments are operated by users themselves on a “self-service” basis following user training and “check-out” by the facility manager, whilst the other is operated by our facility manager on a service basis. The facility is managed by. Dr Phil Mortimer and is located in 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 :
The following links are designed to give an overview of mass spectrometry in general, the services offered by the facility here at JHU Chemistry Department and the instrumentation we have available. We are happy to answer any questions you may have and look forward to hearing from you. We welcome your suggestions for improving the service. What is Mass Spectrometry? – A brief overview of mass spectrometry, it’s principles and applications. Currently under construction. Facility Instrumentation – A description of the instrumentation based within the JHU Chemistry Department facility and its capabilities. Selecting an MS Analytical Method – Guidelines on how to choose which technique to use to obtain a mass spectrum of your sample. Sample Preparation and Submission Guidelines / Forms – Guidelines for preparing samples for mass spectrometric analysis, sample preparation requirements for each technique, and downloadable (pdf format) sample submission forms for the VG-70S high resolution mass spectral service. This section should be read by all prospective users. Instrument Experimental Conditions - Specimen descriptions of experimental conditions for each of the facility’s instruments for inclusion in your publications.
