The laboratory supports research in quantifying individual level exposures to air pollutants including volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs) and particulate matter (PM).  Ongoing laboratory work supports exposure assessment in epidemiological studies using air samples as well as biological samples such as urine, blood and saliva. 

Equipment: 2 Shimadzu HPLC systems, the first with an SIL-10ADVP auto-injector and an SPD-10AVP UV-VIS detector and the second system with a similar injector and an SPD-10AVVP UV-VIS detector; a Shimadzu GC-2010 gas chromatograph coupled with a QP 2010 single quadrupole mass spectrometer (GC/MS); an ABI3000 Liquid Chromatograph Tandem Mass Spectrometer (LC-MS/MS) with an Analysis 1.4.2 software, a Varian Saturn 2200 GC/MS including 3800 GC, 1079 PTV injector with programmable temperature and programmable split/splitless control, CombiPAL liquid and headspace autosampler with solid phase microextraction capability, and Ion Trap Mass Spectrometer with SIS, MS/MS and CI capabilities; two refrigerated micro-centrifuges,  air sampling equipment, refrigerators, -20°C freezers, a water-bath and sonicators.
