The Hoffman Department of Chemistry (located in the Trustee Science Center
) is well equipped with state-of-the-art laboratory equipment. More than $500,000 has been spent for equipment in recent years, including the Nuclear Magnetic Resonance (NMR), Gas Chromatography/Mass Spectrometry (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. This equipment is used for laboratory courses in Analytical Methods, Instrumental Analysis, Organic Chemistry, Biochemistry, Physical Chemistry, Inorganic Chemistry and undergraduate research projects.
There are various applications for this equipment. These include: (1) determination of correct structural formulas (NMR), (2) quantitative determination of trace levels of metals in all types of materials and solutions (AA), (3) determination of net molecular charge as well as the electrophoretic mobility of protein and serum albumin (Electrophoresis), (4) quantitative analysis of the separation of mixtures or organic liquids and determination of molecular weight (GC/MS) and (5) identification of functional groups and determination of the principal structure of the unknown component (FTIR).
