Using Our Instruments

The instruments in the Department of Chemistry mass spectrometry facility are available to all who require them in the course of their work, both from within the Johns Hopkins community, and from outside sources (including academia, commercial, government institutions, high schools, etc.). We welcome enquiries into the use of these instruments.

In order to gain access to these instruments, please first contact the facility manager to discuss your requirements. Users wishing to utilize one of our “self-service” instruments (GC-MS, LC-MS, ESI-MS or Maldi-ToF) will need to participate in a training session on the relevant instrument and demonstrate competence before being issued operating privileges and access credentials. Instrument training is free and is normally conducted on Wednesdays. Users will need to contact the facility manager in advance to set up a training session. Training is normally conducted in small groups of less than three people, due to limited space in the instrument labs. Users will be expected to take comprehensive notes during the training sessions as course-notes are not provided

All users (including those who wish to submit samples for analysis on “full-service” instruments) will need to establish an account with the department for instrument access and billing purposes. To establish an account, please download and complete the Chemistry Core Facility Access Form and return it to the facility manager. A separate form will be required for each user who wishes to use our facilities.

Following successful completion of a training session and receipt of the Facility Access Form, users will be granted access credentials and usage privileges. Users are required to treat all instruments with care and respect and to maintain their competence in order to retain usage privileges. Where a user is considered to be causing a detrimental effect on a particular instrument, additional training sessions may be required by the Facility Manager. In rare circumstances, usage privileges may be withdrawn altogether (usually after several warnings).

For more information or to enquire about the use of our instruments, please contact Dr. Phil Mortimer at the Mass Spectrometry Facility, 410-516-5552,

We look forward to working with you in the future.
