The Center for Applied Isotope Studies (CAIS) provides expert consultation and analytical services for archaeological and paleontological research, specializing in light stable isotopes (δ¹³C, δ¹⁵N, δ¹⁸O), strontium (⁸⁷Sr/⁸⁶Sr), and lead isotopes.
Ancient materials require greater care than modern samples due to their age, preservation state, and complex depositional histories. As such, their analysis is closely coordinated by a multidisciplinary team of experts in archaeology, pretreatment chemistry, and mass spectrometry to ensure rigorous and contextually informed results.
Our dedicated Pretreatment Facility enables a full suite of specialty services, including collagen extraction, bone and enamel bioapatite pretreatment, and high-resolution micro-milling. With over 20 mass spectrometers supporting these analyses, CAIS delivers high-precision, high-throughput measurements across a broad range of sample types.
