<>Capabilities:  Quantitative and qualitative analysis, any sample size and type.  Specializing in water analysis, but also able to handle many other sample types.  From simple wet chemical analysis (titrations, gravimetric analysis) to full instrumental analysis (GC-MS, HPLC, FTIR, AA), I can help find the answers to your chemical problems. 

Consulting Experience: 
                     Development of a SPME-GC-MS method for quantitation of several
                        compounds of interest for Fine Northern Oak, Berlin, WI.
                    Analysis of filter material pore sizes by SEM for W.M. Nugent Co., Niles, IL.
                    Analysis of solid materials contaminating a refrigeration unit by wet
                        chemical methods, FTIR, SEM, and GPC for Kryotech, Columbia, SC.
                    Determination of metal cations by AA for the South Carolina Aquarium, Charleston, SC..
                    Quantitation of calcium, sodium, and boron in a marine extract via AA
                        for the National Ocean Service Marine Biotoxins Program, Charleston, SC.

Other Experience:
                    Utilizing EPA methods for water and sediments - for the analysis of many
                        components in natural waters - metal cations, anions, pesticides, etc.
                    GC-MS identification and quantitation of phthalates, drugs of abuse,
                        constituents in oil and gas, PCB's and PBDE's, dioxins, insecticides
                        and pesticides.
                    HPLC identification and quantitation of caffeine, organic acids, chlorophyll,
                        aspirin, etc.
                    AA and GFAA quantitation of metals in water and sediment.

<>Instrumentation available:
    GC-MS (gas chromatography mass spectrometry) - ion trap MS capable of MSn, EI and CI spectra.
    HPLC (liquid chromatography) system - gradient solvent capability, fluorescence, diode array, and ELSD detection, many column types available including C8, C18, amide-C16, size exclusion (GPC), anion exchange.
    Capillary Electrophoresis system - able to analyze ions (or ionizable molecules) in very small volumes. Various coatings (dynamic and static) available. UV detection (direct and indirect).
     Atomic Absorption - suitable for analysis of most metals.  Also equipped for graphite furnace AA..
    FTIR (infrared) systems - for identification of organic compounds.
    Multiple UV-visible units - for ultraviolet and visible light absorbance measurements.
    Two GC-FID (gas chromatography) instruments - used for volatile organic compounds.
    Scanning Electron Microscope - including gold and carbon coating of samples.
    X-ray - for analysis of metal composition in samples.
    Several pH meters and electronic balances.
    Standard lab equipment and glassware for quantitative analysis.
    Analytical chemical standards for quantitation and verification.

Rates:  Negotiable rates available.  Long-term contracts to one-time analysis.  Donations to the UW-Oshkosh Chemistry department (equipment or $$) offset your cost!
