Experimental and Analytical Geochemistry Lab (EAGL)
EAGL is a geochemical lab in the Department of Geological Sciences at the
University of Michigan that specializes in elemental determination of surface and
groundwaters. The laboratory provides analytical support for researchers both university-wide
and from universities and facilities around the world. The laboratory also routinely tests
waters from a variety of sources including rivers, streams, lakes, ponds and wells, as well as
drinking water. Furthermore, the laboratory can analyze a variety of soils and sediments for
elemental composition. Most of the analyses performed at EAGL are examining the major and minor
components in waters that have weathered Michigan soils. These involve measuring cations such as
sodium, calcium, magnesium, aluminum, and iron, and anions such as chloride, sulfate, carbonate
and nitrate. Instrumentation includes: ICP-OES, gas and ion chromatographs, and wet chemical
analysis systems for measurement of trace and minor element concentrations.
Instruments
- JY Horiba Ultima 2C ICP-OES dedicated to the analysis of cations in aqueous solutions
- Dionex 2000 series Liquid Ion Chromatograph (IC) dedicated to the analysis of anions and organic acids
- Shimadzu TOC5000A for the measurement of inorganic and organic carbon in both dissolved and particulate matter.
- UIC Carbon Coulometer designed to measure a wide range of concentrations of dissolved inorganic carbon in aqueous systems.
- Milestone Microwave Digestion System for the digestion of solids into aqueous media.
- Perkin-Elmer Autosystem XL Arnel Gas Chromatograph dedicated to measuring methane and carbon dioxide.
- Radiometer auto-burette with titration manager designed to measure alkalinity and carbonate concentrations.
- GBC UV/Vis spectrophotometer allows wet colorimetric analyses.
