Dr. Burdige has ~1,400 ft2 of lab space in four laboratories in a lab complex in the Oceanography/Physics Building on the ODU campus. In addition to the major equipment listed below, these labs contain standard laboratory equipment such as balances, a drying oven, a muffle furnace, vacuum pumps, pH meters, O2 microelectrodes and optodes and associated meters and spectrophotometers, a heating/refrigerated cooling bath, several peristaltic pumps, assorted glassware, etc. The Oceanography/Physics Building also has 4 walk-in constant temperature rooms capable of maintaining temperatures from 2 - 30°C.
The major instrumentation in these labs includes:
- a Shimadzu TOC-5000 total carbon analyzer, used for DOC analyses;
- a Dohrmann DN-1900 nitrogen analyzer, used for both nitrate and DON analyses;
- an Ace Glass UV Photo-oxidation system; a FluoroMax-2 scanning excitation-emission spectrofluorometer, with a fiber optics solid sample attachment;
- an HP 8453E diode array UV-Vis spectrophotometer with a sipper cell attachment, and 5 cm path-length cells (open and flow-through);
- a dual pump Rainin HPLC with a Shimadzu RF-530 fluorescence detector;
- an ion chromatography system containing one Rainin HPLC pump and a Dionex conductivity detector (CDM-II);
- a Dionex ion chromatograph with a gradient pump, electrochemical detector, eluent generator and autosampler;
- a Perkin Elmer 330 flame atomic absorption spectrophotometer;
- a Coy anaerobic chamber; a high speed bench-top refrigerated centrifuge with a sea-going gimble stand;
- a UIC model CM5014 CO2 coulometer with acidification and gas sparging module;
- a Brinkmann Metrohm 785 DMP Titrino automated titrator;
- a Carlo Erba ANA 1500 NCS elemental analyzer.
Several Apple Macintosh and Pentium computers (both laptops and desktop models) are available in Dr. Burdige's lab for instrument control, data acquisition, word processing, general data analysis and numerically solving diagenetic modelling problems. These computers are linked to a local area network for e-mail, color printing and Internet access.
The Department of Ocean, Earth and Atmospheric Sciences possesses the following equipment that is used by people working in this lab:
- an Alpchem RFA-300 three channel rapid flow analyzer (with the modules for nitrate, nitrite, ammonium, phosphate and silicate),
- several small boats and motors,
- the 55 foot coastal research vessel R/V Fay Slover ,
- a box corer,
- an Ocean Instruments MC-400 Multi-corer (the small, "lake/shelf" corer capable of collecting 4 cores per deployment)
Old Dominion University also has a stable isotope ratio monitoring mass spectrometer system (IRMS) purchased with funds awarded by the NSF Major Research Initiative (MRI). This instrumentation is housed in the Dept. of Chemistry and Biochemistry at ODU (in Dr. Robert Dias' lab). This system allows for the natural abundance determination of 13C/12C, 15N/14N, 18O/16O, 34S/32S and D/H in liquid, solid and gaseous samples in nanomolar quantities. The instrumentation consists of a Europa GEO20-20 dual inlet IRMS, a gas chromatograph combustion/pyrolysis interface for the isotopic determination of individual organic compounds, an elemental analyzer for the isotopic determination of bulk organic and inorganic materials, a carbonate preparation device, and a headspace sampler / equilibration unit for the determination of dissolved inorganic carbon, water and headspace gas samples. The isotope laboratory is also outfitted with a high-vacuum sample preparation line for the preparation of light gases for isotopic analysis. |
