SIRFER consists of multiple isotope ratio mass spectrometers and isotope ratio infrared spectrometers capable of providing bulk and trace gas analyses.


Since 1986, SIRFER has operated as an open facility that provides stable isotope ratio analyses.


SIRFER provides high quality analysis and service in a timely fashion. We have developed reference materials relevant to the different kinds of samples analyzed. Data must meet or exceed our high quality control standards.


SIRFER is also an educational and training facility. We provide a series of summer courses to complement the undergraduate classes in stable isotope biogeochemistry and ecology offered during the academic year.


From 8th graders measuring isotopes in the food they eat, to undergraduates in an organic gardening class measuring isotopes of foods they grow, SIRFER helps expand public interest in science. Young minds learn the excitement of science by doing.
