THE WALTER H. HOFFMAN DEPARTMENT OF CHEMISTRY IS EQUIPPED WITH MANY STATE OF THE ART SCIENTIFIC INSTRUMENTS: 
More than $500,000 has been spent for equipment in recent years, including the Nuclear Magnetic Resonance (NMR), Gas Chromatograph/Mass Spectrometer (GC/MS), High Performance Liquid Chromatograph (HPLC), Fourier Transform Infra-red Spectrophotometer (FTIR), Atomic Absorption Spectrophotometer (AA), Electrophoresis, Differential Scanning Calorimeter (DSC), Ultracentrifuge, Polarimeter, and Fluorimeter. These equipments are used for laboratory courses in Analytical Methods, Instrumental Analysis, Organic Chemistry, Biochemistry, Physical Chemistry, Inorganic Chemistry and undergraduate research projects. A broad list of instruments is given below.
