The Ar Laboratory at MIT's Department of Earth, Atmospheric and Planetary Sciences (EAPS) provides facilities for measurements using the ⁴⁰Ar/³⁹Ar technique to investigators in both the academic and commercial fields. The laboratory can measure ⁴⁰Ar/³⁹Ar ages using various techniques (described below) on a wide range of materials over a wide range of ages and sample sizes. Data quality is continually monitored by frequent calibrations against argon in air and the use of a number of well-established standards. Investigators are provided with reports of the results with varying degrees of detail depending on their needs.

The laboratory is open to both students and professionals who may wish to participate in the analyses of their samples. We can also provide information and help with the use of the ⁴⁰Ar/³⁹Ar technique in various situations.
