OUR LABORATORY



Arndt Schimmelmann joined the Department of Earth and Atmospheric Sciences at Indiana University in 1993 and installed a vacuum line capable of processing organic materials off-line, to collect and quantify carbon dioxide, nitrogen, and elemental hydrogen. A couple of years later John M. Hayes and Alex L. Sessions were developing compound-specific hydrogen stable isotope mass-spectrometry at Indiana University and were in need of a few pure   n-alkanes with known hydrogen stable isotope ratios. Our initial supply of pure n-alkanes began the long list of compound-specific reference materials that were subsequently shared with external users. Our reference materials are in use by hundreds of laboratories on all continents except Antarctica.

The Department of Earth and Atmospheric Sciences at Indiana University has been distributing Indiana Zinc for the reduction of water to elemental hydrogen for about 30 years to hundreds of users worldwide. The art of producing Indiana Zinc has been passed on from one worker to the next.
