Mass spectrometry is a powerful analytical technique for the identification, characterization and quantification of minute quantities of analytes in pure form or in complex mixtures. The North Carolina State University Mass Spectrometry Facility (NCSU MSF), located in the ground floor of Dabney Hall, offers several mass spectrometers providing analysis through an array of methods for sample introduction, ionization and mass measurement.
Our mass spectrometers include the following: (1) Thermo Fisher Scientific Exactive Plus MS; ESI with a mass range of 50 - 6,000 m/z; resolution: > 17,500 - 140,000 FWHM (200 m/z); mass accuracy: < 1 ppm RMS internally calibrated (2) Agilent Technologies 5975 GC/MS; EI, CI, NCI with a mass range 2 - 1,000 amu (3) AB Sciex 5800 MALDI-TOF/TOF MS; mass range of 0 - 200,000 m/z; resolution: > 33,000 FWHM (2,465 m/z).
An array of services are provided to all University faculty, staff and students in the investigation of biological analytes such as peptides, proteins, oligonucleotides, lipids and carbohydrates, as well as synthetic polymers and small molecules. Due in no small part to the critical information that mass spectrometry provides to investigators in the physical and life sciences, the NCSU MSF serves to promote scientific inquiry at the crossroads of diverse disciplines. The MSF is directed by a full-time mass spectrometrist - Dr. Taufika Islam Williams.
