The workhorses of our research are gas chromatography–mass spectrometry (GC-MS) for volatile and semi-volatile contaminants and liquid chromatography–mass spectrometry (LC-MS) for hydrophilic contaminants.
Gas Chromatography–Mass Spectrometry
Provided by Department of Chemistry & Biochemistry Core Facility
Custom-built Photoreactor
For the photodegradation experiment, we use the set of light in UVA- and visible spectral zone.
Sample Preparation
We have a range of instrumentation for extracting organic contaminants from water samples, cleaning up the extracts, and preparing them for mass-spectrometry analysis — including solid-phase extraction, liquid-liquid extraction, and nitrogen evaporation equipment.
Solid-Phase Extraction
Solid-Phase Microextraction
With Auburn University
GC–Isotope Ratio Mass Spectrometry (IRMS)
We use GC-IRMS for measuring carbon and hydrogen isotopes to trace the transformation mechanisms of organic contaminants.
With National High Magnetic Field Lab
FT-ICR Mass Spectrometry
Fourier Transform Ion Cyclotron Resonance Mass Spectrometry for the characterization of DOM structures.
Additional instrumentation available through core facilities includes UV/VIS, fluorescence spectrometer, FTIR, and NMR instruments.
