Analytical Core

The UK CARES analytical core is equipped with a range of GC and LC coupled mass spectrometer systems including multistage and high resolution instruments.  These instruments are used for quantitation of small molecules of broad relevance to environmental disease researchers. 

The laboratory contains two Agilent GC MS systems with quadrupole and triple quadrupole mass analyzers as well as electron capture and flame ionization detectors.  It contains three ABSciex triple quadrupole linear ion tram mass spectrometer systems with Shimadzu HPLC and UPLC systems as well as an ABSciex quadrupole time of flight mass spectrometer system with HPLC and microflow chromatography systems and a Thermo Q-Exactive quadripole orbitrap mass spectrometer with a dionex UPLC system.  

The laboratory is also well equipped for sample preparation from biological and environemental matrices with automated systems for solid phase and accelerated solvent extraction as well as solvent evaporation including several Caliper Turbovap evaporators and a large volume genevac solvent evaporator.

The laboratory can conduct measurements of many different classes of pollutants in biological or environmental matrices including serum and blood plasma, tissues, water and soil.  Particular areas of emphasis include polychlorinated biphenyls, dioxins, polychlorinated benzodifurans, per- and polyfluoroalkyl substances, and bisphenols.  Published methods for other established and emerging persistent organic pollutants and biomarkers of exposure to these pollutants can be set up and validated for use in preclinical or clinical studies as needed.
