Chemistry faculty and students carry out experiments using an extensive array of state-of-the-art instrumentation for molecular structure determination, spectroscopy, chromatography, and other specialized techniques. Significant instrumentation in the department includes a liquid chromatography electrospray ionization quadrupole time of flight mass spectrometer (LC-ESI-MS) used to study the structure and composition of lipids and proteins, a charge-coupled device (CCD) dual source X-ray diffractometer used to determine the three-dimensional arrangement of atoms in molecules, and an atomic force microscope (AFM) used to measure interactions between biological molecules. Other recent acquisitions include a new 400 MHz nuclear magnetic resonance (NMR) spectrometer used to determine the structure of organic molecules and a scanning electron microscope (SEM) for analysis of nanomaterials.
