The 91社区 Chemistry Department Mass Spectrometry Facility (MSF) offers a comprehensive range of mass spectrometry techniques to researchers, using six mass spectrometers equipped with a range of ionization methods. The facility鈥檚 primary role is to support chemical research conducted within the Department; but can also serve other 91社区 departments, as well as outside academic and industrial groups.
Some of the instruments can be operated by our department users themselves following user training e.g. LCQ, Scion and Polaris Q.
The MSF is located in room 21聽in the basement of the Department. Everyone is encouraged to use the services offered at the Facility and to get in touch with its personnel to discuss your questions in details.
A sample submission request form has to be filled when a sample is submitted for analysis. sample_submission_request_form.docx
