Chemistry involves the study of matter at the atomic and molecular level. Concepts and tools of chemistry are used to study the composition, structure, reactivity and energy changes of materials in the world around us. At PLU, students will find a chemistry program that supports their interests, whether in the chemistry of natural products, the environment, biological systems, polymers, or inorganic compounds, and that supports their educational goals, whether toward graduate study, the medical and health professions, biotechnology, education, business, or as a complement to other studies in the natural sciences, humanities, or social sciences. For good reason, chemistry is often called “the central science.”
The Chemistry Department’s courses, curriculum, faculty, and facilities are approved by the American Chemical Society.
Student have hands-on use of sophisticated instrumentation in coursework and research with faculty, including 500 MHZ Fourier transform nuclear magnetic resonance (FTNMR) spectroscopy, atomic force microscopy (AFM), inductively coupled plasma atomic emission spectroscopy (ICP AES), spectrofluorometry, differential scanning calorimetry (DSC), Fourier transform infrared (FTIR) and Raman spectroscopy, laser light scattering instrumentation, gas chromatography with mass selective detection (GCMS), high performance liquid chromatography (HPLC) with ion trap mass selective detection (LCMS), and Linux workstations for molecular modeling and computational chemistry.
Faculty research projects involve undergraduate participation.
