The High Precision Isotope Ration (HiPIR) Consortium was a loose affiliation of individuals interested in the development of analytical techniques for high precision isotope ratio measurements. The activities of this group culminated in 2007 when it organized a short course in Inorganic Ratio Mass Spectrometers. The materials generated for this short course are provided below.
Introduction to Inorganic Isotope Ratio Mass Spectrometry
The materials on these pages are provided courtesy of the instructors (Bill Olszweski, EAPS/MIT; Tony Appelhans, Idaho National Laboratory; Gary Hieftje, Indiana University) of a 5-day short course in Inorganic Isotope Ratio Mass Spectrometry held at the U.S. Geological Survey, June 18-22, 2007. The course was organized by the High Precision Isotope Ratio (HiPiR) Consortium and was supported by the Earth Sciences Division, Instrumentation and Facilities Program at the National Science Foundation and by the Cooperative Institute for Research in the Environmental Sciences (CIRES) at the University of Colorado, Boulder. Course materials presented include Powerpoint presentations of various topics relating to isotopic ratio mass spectrometers, and exercises relating to the use of the ion optics simulation software, SIMION. Of course, you will be able to make best use of the SIMION models available here by obtaining a copy of SIMION. Even without the SIMION software, however, there are companion Powerpoint presentations relating to ion optics that provide much useful information.
Each of the below links will take you to a separate page relating to specific topics in Isotope Ratio Mass Spectrometers. On these pages you will find descriptions of the topics covered and links for downloading Powerpoint presentations, SIMION models, and various text documents. Happy perusing!
