Full scan analyses and accurate mass measurement are available.Īn HP GC/MSD is a dedicated GC-EI MS low resolution instrument for routine GC/MS analyses of volatile and semi-volatile organic compounds including reaction mixtures. FD is a powerful tool for the analysis of small polymers and other non-polar materials (<4000 Da). EI, CI, and FI techniques are suitable for volatile and semi-volatile organic compounds with sample introduction via an Agilent capillary GC or by direct insertion probe for thermally labile compounds. Software is available for the analysis of polymer data.Ī Waters GCT Premier Time-of-Flight MS is equipped with electron ionization (EI), chemical ionization (CI), and field ionization/field desorption (FI/FD) ion sources. Additionally the instrument is capable of mass spectral imaging and post source decay analysis. The Microflex LRF has a mass range of up to 20,000 Da in reflectron mode or up to 500,000 in linear mode. Facility staff is available for operator training as well as consultation on experimental design and data interpretation.Ī Bruker Microflex LRF MALDI TOF mass spectrometer is used for the analysis of a broad range of compounds including small molecules, peptides, proteins, nucleic acids, and synthetic polymers. Services are available by sample submission to the facility staff or by direct instrument access for trained users on a 24/7 basis. Chemical structure may be probed by fragmenting molecular ions and mass measuring the resulting product ions.Ī wide range of ionization techniques and capabilities are available. This family of techniques measures the masses of organic and biological molecules by creating gas phase ions from the analytes and manipulating those ions in electric and magnetic fields. Mass Spectrometry is a primary tool for structure elucidation, molecular weight determination and molecular formula confirmation for organic and biological materials. The Department of Chemistry and Biochemistry operates an in-house Mass Spectrometry facility to support research and teaching activities.
