The Center for Applied Isotope Studies is the oldest AMS radiocarbon & stable isotope laboratory in the world (est. 1968) that is ISO/IEC 17025:2005 accredited. 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.
Mona, a new postdoc at CAIS’s Laboratory, takes avocados, spikes them with pesticides, and then runs various procedures to compare the quality of results from one method to the next. Why?
“Do you know radiocarbon dating?” Dr. Alex Cherkinsky, a senior research scientist at CAIS.. He searches his desk for pen and scrap paper. “I will show you. If you’re going to work here you should know.”
“I never felt more connected to the people I’m studying than when I was out in this big bay in waste-deep water [collecting shells], and I look around and kids are doing the same thing with their parents.” Carla said.
