Chemistry

The Olin Center for Physics and Chemistry features more than 20,000 square feet of classroom, laboratory, and study space. It includes a lecture demonstration arena; well-equipped general, organic, analytical, biochemistry, physical chemistry, and inorganic laboratory facilities; a chemistry data analysis room that includes computer facilities for poster preparation; an organic instrumentation room; special laboratories for student and faculty research; three seminar-classrooms; a conference room; and a student lounge. The department received funding from the the National Science Foundation (NSF) and the Murdock Trust for a high-field NMR spectrometer that is used by all chemistry students.

Instrumentation

Nuclear Magnetic Resonance Spectrometer

The 600 MHz Bruker Avance NEO NMR spectrometer is equipped with broadband and three channel (HCN) probes and is used extensively in organic chemistry, biochemistry, and physical chemistry laboratory courses. It also supports the research of several faculty members from Lewis & Clark and nearby institutions. If you are interested in using this system, please contact the chemistry department to find out how to gain access to it.

 

High Pressure Liquid Chromatograph

Interfaced to a diode array UV-Vis detector, a fluorescence detector, and a fraction collector, our Shimadzu Prominance HPLC is useful for analyzing complex mixtures and purifying samples. 

 

 

Fourier Transform Infrared Spectrophotometers

Nicolet 360 and 380 FTIR spectrometers, are used in the identification of compounds made in organic chemistry and advanced labs. 

 

Diode Array UV/Vis Spectrophotometers

Students throughout the chemistry curriculum use the department’s four Hewlett-Packard ultraviolet-visible diode array spectrometers and six Ocean Optics spectrometers to analyze liquid samples.

 

Nanodrop Spectrophotometer

A Thermo-Scientific Nanodrop 2000c is used in biochemistry laboratory courses for measuring protein and DNA concentrations, and the optical density of cell cultures.

 

 

 

Scanning Electron Microscope

The FEI Phenom scanning electron microscope is used to image samples at a resolution in excess of what can be achieved with optical microscopes. The instrument is used in inorganic chemistry and nanomaterials chemistry courses. 

 

Polarimeter

An Atago AP300 Digital Polarimeter is useful for measuring how chiral compounds rotate the angle of polarized light.

 

Gas Chromatograph - Mass Spectrometer

A Varian Saturn 2100T mass spectrometer interfaced to a Varian 3900 gas chromatograph is used to identify substances in complex mixtures.

 

Confocal Raman Microscope

The Horiba XploRa confocal Raman microscope can be used to identify substances in such materials as bone, tissue, soil, solar cells, paintings, sculptures, and ancient manuscripts.

 

 

Dynamic Light Scattering

Our Malvern Zetasizer ZS90 uses dynamic light scattering to measure nanoparticle size and zeta potential (the extent of electrostatic charge/repulsion between particles in solution). 

 

                   

 

Molecular Modeling Laboratory

Twelve quad-core 27” iMacs are used in general, organic, and physical chemistry courses to run Spartan and Odyssey software for modeling molecules and systems of molecules.

 

 

 

Gas Chromatographs

Three Gow-Mac gas chromatographs are used for analyzing fats in foods for the Nutrition labs.

 

 

 

Data Collection Stations

Twenty-four Macbook Pro laptops equipped with Vernier LabPro data-collection interfaces are used in the General chemistry lab for automated collection of routine data.
