Research Facilities

X-Ray Laboratory

The x-ray laboratory, renovated between 2000 and 2002, is used for mineral identification and geochemical analysis of rocks, soils, and sediments. The laboratory contains space for sample preparation and has a large array of geochemical and mineral standards. The major instrumentation includes:

12. Philips X-Ray Diffractometer
13. Philips PW2400 X-Ray Fluorescence Spectrometer

Philips PW2400 X-Ray Fluorescence Spectrometer
Measures the major and trace element composition of rocks and soils. Samples are crushed and powdered and then made into either glass fusion disks or pressed powdered pellets for analysis.

Philips X-Ray Diffractometer
Identifies mineral composition of fine-grained rocks, soils, and sediments. Samples are powdered and then mounted on a glass slide for analysis.

Biogeochemistry Laboratory

The biogeochemistry laboratory, renovated between 2000 and 2002, contains instrumentation for the chemical analysis of natural waters. Much of the data collected in this laboratory is used for interpreting the biogeochemical cycling of elements in forested and urban watersheds. The laboratory is well equipped with an exhaust hood, volumetric glassware, adjustable pipettors, balances, sonifier, a refrigerator for sample storage, and drying oven. The major instrumentation includes:

1. Accumet AR25 Benchtop pH Meters
2. Drying oven
3. Hach DR/4000V Spectrometer and LaMotte 2020 Turbidometer
4. Fume Hood
5. Perkin Elmer 2400 Series II CHNS/O Analyzer
6. O.I. Analytical Flow System IV Autoanalyzer
7. Turner Designs AU-10 Fluorometer
8. Dionex 120 Ion Chromatograph
9. Tekmar-Dohrman Phoenix 8000 Total Organic Carbon Analyzer
10. Balances, Sonifier, and Pipettes
11. Barnstead Nanopure Diamond Water Polishing System
12. Labconco Water Polishing System
