Facilities & Labs

Laboratories

Geochemistry

Three laboratory spaces (about 2,200 square feet) exist in the basement level of Hamilton Hall (B07, B08, and B09). These labs are dedicated to the analysis of soil, water, and rock geochemistry and the mineralogical compositions of rocks. These facilities include extensive bench space, available gas, vacuum and air lines, fume hoods, and wireless internet access. The labs are also equipped with a Barnstead pure water system. Additional laboratory spaces on the 2nd floor (about 1,200 square feet in total) are dedicated to sample preparation and analysis via isotope ratio mass spectrometry and Rock-Eval pyrolysis.

Instrumentation

ICP-OES (PerkinElmer Optima 8300)

Optima 8300 InstrumentThe Optima 8300 is a bench-top, dual-view ICP-OES with two solid-state SCD detectors, allowing measurement in the same run of high and low concentrations of a variety of samples for enhanced productivity and accuracy even with complex matrices.  The detection limits is about 0.5uM depending on the element being analyzed and the sample matrix.  The instrument gives a linear response over 3-4 orders of magnitude in concentration (e.g., 0.1 - 500 mM Mn).

Thermo Scientific Niton portable XRF analyzer

The XRF offers a rapid, nondestructive method for analysis of soils and sediments.

Applications for the instrument range from the analysis of rock core and cuttings for petroleum exploration to the evaluation of polluted soils and sediments.

 
IC (Dionex ICS-2000)

IC Dionex InstrumentThe ICS-2000  is a totally integrated and preconfigured Reagent-Free (TM) Ion Chromatography system.  It can be used for both major anions and cations analyses.  Currently, it has been set up for anion analyses (fluoride, chloride, bromide, nitrite, nitrate, sulfate and phosphate).


Stable Isotope IRMS (Thermo Delta V Advantage)Stable Isotope I R M S

Our Thermo Delta V Advantage mass spectrometer is connected with a Elemental Analyzer (Flash EA 1112).  It is available for use to collect data of carbon, nitrogen, hydrogen, and oxygen isotopes and elemental concentrations. Learn more from Dr. Schubert's lab through his website.


Rock-Eval 6

Rock Eval 6The Rock-Eval 6 analyzer from Vinci Technologies is designed for the characterization of organic matter in petroleum source rocks, although it can alternatively be used for environmental studies. The instrument is a completely automated device consisting of separate pyrolysis and oxidation ovens. Concentrations of hydrocarbon and oxygen-bearing gasses (i.e., CO2 and CO) generated during pyrolysis (and later via oxidation) are measured as a function of heating temperature and time using FID and IR detectors, respectively. The resultant data can be used to assess the type, amounts, thermal maturity, and kinetic behavior of organic matter.  


XRD (DIANO 2100-E)

X R D X ray diffractometer

The DIANO 2100E Xray Diffractometer is used to identify crystalline compounds qualitatively and quantitatively if standards are available. 

Data collection, display and manipulations are easily done with Diano's XSPEX software.

Paleomagnetics Laboratory

The School of Geosciences houses a paleomagnetism and rock magnetism laboratory with instruments for advanced paleomagnetic and rock magnetic investigations. The main instruments include: Princeton Measurements Vibrating Sample Magnetometer VSM 3900-04, 2G Superconducting Rock Magnetometer 755-1.65, AGICO JR-6 Spinner Magnetometer, a DTech-2000 alternating field demagnetizer with ARM and pARM attachment, and two ASC TD48SC thermal demagnetizers. Rock magnetism instruments include an AGICO Kappabridge KLY-3S and a KLY4-S, a Sapphire Instruments SI-2B magnetic susceptibility and anisotropy meter, a Bartington MS-2 with MS2B sample sensor, field loop and MS2C core logging sensors (80 and 125 mm), ASC IM-10 and IM-10-30 Impulse Magnetizers, KT-9 and SI30 portable susceptometers.

Sedimentary Geology Laboratory

The Sedimentary Geology laboratory is situated in Hamilton Hall 109 and is dedicated to the processing and analysis of sedimentary rocks and well cores. It houses 120 linear feet of benches for cores examination, a collection of sedimentary rocks specimens, a Winx vibracore drill for on-land use, an extensive thematic library, and a meeting area. Additionally, the laboratory has a detached microscopy room.

Auxiliary Units

The School of Geosciences manages the Ira Nelson Horticulture Center and Cade Farm, which function as off-campus research and education facilities. The UL Lafayette Research Farm at Cade is in St. Martin Parish and consists of 600 acres of crawfish ponds, pasture lands, agricultural lands, and wetland habitat. The Welcome Center building includes a large classroom that can accommodate up to 75 people. A field-based coastal wetland research laboratory is also being developed at Cade Farm. Plumbing, pumps, and storage ponds will be used to provide the wetlands with different salinity and tidal regimes that mimic different ecosystems of coastal Louisiana.

The Ira Nelson Horticulture Center is an instructional horticulture and experimental laboratory facility designed to educate students and the community. The center consists of 16,763 square feet of greenhouses; 4,668 square feet of shade houses; and 7,030 square feet of offices, classrooms, laboratories, and storage.
