Dr. Nelson Zhao 

Welcome to the Analytical Services for the UNF Department of Chemistry

The Analytical Instrumentation Facility houses a number of advanced analytical instruments which can be used to analyze numerous samples for you. Our instruments include NMR, FTIR(Solid and Liquid), UV-Vis, AA, GC, GC/MS, and XRD.

Our services are available at reasonable prices. Whether it is a simple sample analysis, method development, or a more complicated structural elucidation, quality work is provided in a timely fashion.

Click the instrument below for rate information. The charges are on a per sample or per hour basis depending on the instrument involved. 

For special requests such as NMR data interpretations, analyses requiring the use of several instruments, complex mixture analysis, etc., please contact Nelson Zhao at (904) 620-1962 or by email at nelson.zhao@unf.edu .

• Nuclear Magnetic Resonance Analysis (NMR)

  The NMR lab is equipped with a Agilent VNMRS 500 MHz Nuclear Magnetic Resonance instrument.

   

  Solution Probes:

   

  • ¹H-¹⁹F/¹⁵N-³¹P 5 mm PFG AutoX Dual Broadband Probe for ¹H, ¹⁹F , as well as other nuclei in the resonance frequency range between 50 MHz (¹⁵N) and 202 MHz (³¹P).
  • ¹H-¹⁹F{¹³C} 5mm Triple resonance PFG probe; indirect detection with high sensitivity for ¹H and ¹⁹F.

  Both probes have VT capability between -80°C and +120°C. In addition to 1D ¹H, ¹⁹F, ¹³C, ³¹P, ²⁹Si NMR experiments, the instrument can acquire APT, DEPT, and 2D experiments such as COSY, TOCSY, NOESY, HSQC, and HMBC.
