The Chemistry Department at Pittsburg State University strives to keep itself well-equipped with modern instruments and computers. The philosophy of the department is that all instruments are available for hands-on use by chemistry students in their courses and research.
The Kansas Polymer Research Center (KPRC) of the Business and Technology Institute (BTI) is located in the Tyler Research Center. These labs are very well equipped for polymer research. Dr. Petrovic (Professor of chemistry), Dr. Javni (Adjunct Professor of Chemistry), and Dr. Guo (Adjunct Professor of Chemistry), are located at the KPRC and often make their instrumentation available for chemistry student use.
Departments at Pittsburg State University have an history of cooperating in the use of instrumentation. Chemistry students generally find the Physics Department and Biology Department willing to share their instrumentation.
The Department has two modern NMR spectrometers operating at 60 and 300 MHz for protons.
Two Fourier-Transform Nuclear Magnetic Resonance spectrometers are located in Room 108 Heckert-Wells. Both instruments are used in teaching and research by students and faculty at PSU. The Chemistry Department welcomes inquiries into the use of these instruments by faculty at colleges and universities in this region and beyond. Appropriate use of these instruments by students and faculty visiting from other institutions is encouraged.
60 MHz Proton NMR
The 60 MHz Proton NMR spectrometer consists of a Varian EM-360 permanent magnet and an upgrade of the electronics by Anasazi Instruments. This instrument provides a way to introduce students to modern FT-NMR spectrometry. The "NUTS" software permits advanced NMR data processing. The instrument provides excellent low-field proton spectra of organic compounds. Relaxation time measurements and two-dimensional COSY experiments can also be performed.
Bruker DPX-300 NMR
The Bruker DPX-300 NMR spectrometer is an advanced instrument purchased in 1998 for $250,000 with the help of a grant from the National Science Foundation. The 7.05 Tesla superconducting magnet gives proton (H-1) spectra at 300 MHz and Carbon-13 spectra at 75 MHz. Dozens of different one- and two-dimensional experiments are possible with this instrument. The broadband probe for liquid samples permits spectra to be taken of many nuclei besides C-13 and H-1.
An important feature of the instrument is that it can be used to study solids with its Cross- Polarization/Magic-Angle-Spinning (CP/MAS) probe. Carbon-13 spectra of solid samples such as polymer powders are routine. The CP/MAS probe can also be used for spectra of many other nuclei. Both solids and liquids experiments can be carried out over a wide temperature range.
A Shimadzu GC/MS [GC17A Gas Chromatograph with a QP5000 Mass Spectrometer detector is a workhorse for the organic chemistry laboratories. The GC separates mixtures of compounds and then a mass spectrum can be obtained for each compound. To the left of the GC/MS is a Tekmar LSC 2000 for concentrating water contaminants before analyzing them with the GC/MS.
An ISO FluoroMax-Fluorometer is an important instrument for the Biochemistry research lab
A GBC 908 Atomic Absorption Spectrometer is a key instrument in the Analytical Lab. Low concentrations of metals are detected with this instrument.
The Department has two Fourier-Transform Infrared Spectrometers. The Thermo Nicolet IR-300 gets heavy use in the Organic Chemistry Labs for the identification of organic compounds. An ATR attchment makes it easy to take IR spectra of solids.
The second FT-IR spectrometer is a Mattson Research Series FTIR. This instrument has a sensitive MCT detector that makes it useful for studies of compounds adsorbed on surfaces.
The Chemistry Department has an Atago AP-100 Polarimeter. This instrument is used in organic chemistry to determine optical rotation of mirror image isomers.
The Chemistry Department has its own computer lab in Room 121 Heckert-Wells. The computer lab is adjacent to the main chemistry lab for General Chemistry and Organic Chemistry. When a chemistry lab calls for computer analysis of data, the computer lab is reserved for use by that lab class.
The Department uses the Vernier Software "Calculator Based Laboratory" (CBL) System to bring instrumentation to the General Chemistry laboratories. Sensors are available for the measurement of temperature, pressure, pH, conductivity, and visible absorbance. The data is collected on a TI-83 graphing calculator in the chemistry lab and then downloaded into a computer in the adjacent computer lab.
