The Chemical and Trace Analysis Lab housed in the Department of Chemistry and Physics has a wide variety of scientific instrumentation available for our students and faculty. Although many facilities and research groups may have thier own equipment, the 20+ pieces of instrumentation in the analysis lab are available to WCU affiliates with no time-of-use charges thanks to funds from the student technology fee. Non-CHPH users and users conducting research are asked to provide their own consumables.
Through our partnership with the WCU Corporation for Entrepreneurship and Innovation, students and faculty in the Chemistry and Forensic Science Programs can provide routine analysis and method development services to outside organizations. The rates will vary depending on the size and scope of the work. Please contact us for more details.

The department maintains several FT-IR instruments including a Smith's Detection FT-IR, a Perkin Elmer SpectrumTwo FT-IR, and a Perkin Elmer SpectrumOne FT-IR. All of these are quipped with a diamond attenuated total reflectance cell (ATR), and the latter two can also be used for traditional transmission FT-IR. The instrument pictured right is a Perkin Elmer SpectrumOne.
The deparment also maintains a Thermo/Nicolet iS10 FT-IR reserved for microscale FT-IR and gas-phase FT-IR (see below).
Note that the Smith's Detection instrument and the SpectrumTwo are reserved for undergraduate and graduate organic chemistry labs.

The Horiba LabRam HR allows users to perform both macro- and micro-Raman spectroscopy as well as remote Raman spectroscopy via a fiber coupling. With XY step sizes of 0.1µm and Z steps of 0.5µm, the confocal microscope system can collect Raman images with micron resolution. A collection of 4 lasers (including the argon ion laser seen below) provide excitation across the visible spectrum.
The Raman spectrometer was funded through a grant from the National Science Foundation.
The Agilent Cary 5000 UV-vis-NIR (pictured right) is a monochromated dual-beam UV-visible-NIR spectrometer that provides wavelength coverage from 173 - 3300 nm.

The Agilent 1220LC features a dual channel gradient pump, 100 position autosampler, and variable wavelength detector.
The Ultimate 3000 was funded through a grant from the North Carolina Biotechnology Center.
Our Thermo Finnigan LTQ linear ion trap mass spectrometer has both electrospray and atmospheric pressure chemical ionization capabilities as well as an internal collision cell for MS n experiments. Users may either directly inject their sample into the ionization chamber or first separate complex mixtures using the coupled Dionex Ultimate 3000 HPLC with tertiary gradient pump and 400 position autosampler.
The Dionex ICS-1600 Ion Chromatograph can be used to separate ions in a solution based on their charge. The ICS-1600 is setup to analyze anions.
The department maintains a Malvern Zetasizer Nano ZS This utilizes a 633 nm HeNe laser to measure the optical properties of suspensions. This instrument can be used to measure Particle size, Molecular weight, and Zeta potential.
