CRITCL Mass Spec
Mass Spectrometry CORE Laboratory
The UNC Department of Chemistry Chemical Research Instrumentation Teaching and Core Laboratories, CRITCL, Mass Spectrometry laboratory specializes in small molecule analysis. Our services include, but are not limited to, quantitative mass spectrometry, liquid chromatography separations, fragmentation and structural elucidation, MS/MS, & MSn, mass spectrometry, complex mixture analysis, molecular formula confirmation, high resolution and accurate mass, analysis, & trace metal determination/quantitation.
The mass spectrometry laboratory provides individualized user training for undergraduate, graduate, and post-doctoral scholars of the Department of Chemistry. In addition, the facility aims to provide the highest quality mass spectrometric services possible to members of the UNC Chapel Hill Department of Chemistry, UNC campus community and surrounding Research Triangle areas.

Director Mass Spectroscopy Laboratory
Brandie M. Ehrmann, Ph.D.
Caudill Laboratories 052 – Office
Dr. Brandie Ehrmann, a mass spectrometrist with expertise in ultra-high resolution mass spectrometry and complex mixture analysis, operates the Mass Spectrometry Division of the Chemical Research Instrumentation Training and Core Laboratories, CRITCL, within the UNC Department of Chemistry. Dr. Ehrmann received her PhD. in Analytical Chemistry from Florida State University in Tallahassee, FL, in 2010. She worked for Dr. Alan Marshall, co-inventor of Fourier transform ion cyclotron resonance mass spectrometry. Her research dissertation focused on crude oil analysis; specifically, emulsion formation, emulsion breaking, and asphaltene speciation. Dr. Ehrmann joined UNC & the Department of Chemistry in January 2015. She is assisted by Evan McConnell, a departmental graduate assistant in the Hicks Group, and Paul Soma, a graduate assistant in the Glish Group. Evan and Paul handle routine analyses, assists with student training, and routine instrument maintenance procedures.
Paul Soma, Ph.D. Candidate
Glish Group Member, Caudill Laboratories 323
Area of Research: Investigating the conformational space of gas-phase ions and ion-molecule interactions with ion mobility-mass spectrometry.
Sample Submission and Training
There are two possible mechanisms for having samples analyzed in our facility. Samples can be submitted for analysis on a fee for service basis or students can, following required training, run their own samples on our instrumentation. Please contact Dr. Brandie M. Ehrmann for more information. We provide students/scholars with assistance in experimental design, data acquisition, and data analysis.
