About Us

The Center for Applied Isotope Studies is the largest and oldest ISO/IEC 17025:2005 certified Isotope Geochemistry Laboratory/Radiocarbon AMS Dating Facility in the United States. Our commitment to experiential STEM education, research excellence, and superior service sets us apart from for-profit businesses. As an interdisciplinary research center, our scientists are experts in physical chemistry, geology, marine science, physics, archaeology, ecology and biology. This means that CAIS researchers are able to effectively collaborate in research programs and participate in method development for myriad of industrial and academic applications.

Our analytical capabilities include accelerator mass spectrometry (AMS), stable isotope ecology, natural products and biobased product testing, organic compound and biomarker analysis, and elemental analysis by X-ray fluorescence and inductively coupled plasma mass spectrometry and optical emission spectrometry (ICP-MS and ICP-OES. Additionally, CAIS has recently acquired a high-resolution multiple collector ICP-MS (HRMC ICP-MS) capable of very high precision quantification of most isotopic systems.
