Agilent Gas Chromatograph (Model 7890A) Mass Spectrometer (Model 5975C) dedicated to electron impact ionization methods (GC/EI-MS). This instrument is one of our work horses in our laboratory, dedicated to the analysis of sample extracts for a large suite of semi-volatile organic compounds, including organophosphate flame retardants, organochlorine pesticides, polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs) and phthalates.
Agilent Gas Chromatograph (Model 6890N) Mass Spectrometer (Model 5975) dedicated to chemical ionization methods (GC/ECNI-MS). This instrument is another one of our work horses, and is dedicated to the analysis of sample extracts for brominated flame retardants (e.g. PBDEs) and fluorotelomer alcohols (i.e. FTOHs).
Agilent Gas Chromatograph (Model 7890B) Quadrupole Time of Flight Mass Spectrometer (QTOF; Model 7200). This is a relatively new addition to our laboratory, and is supported through a collaborative agreement with Agilent Technologies. The QTOF is utilized for more exploratory based research projects, to identify unknown compounds using accurate mass analysis and fragmentation patterns, and for developing non-targeted analytical methods.
Agilent Liquid Chromatograph (Model 1260) Tandem Mass Spectrometer (Model 6460). This instrument is used to analyze sample extracts for more polar analytes, including urinary metabolites of organophosphate flame retardants. We also use this instrument to monitor and quantify phenolic contaminants, hydroxylated polybrominated diphenyl ethers (e.g. OH-BDEs), perfluorinated carboxylic acids (e.g. PFOA) perfluorinated sulfonic acids (e.g. PFOS), and thyroid hormones (e.g. T4, T3 and rT3) in a variety of sample matrices.
