A fully automated MAP 215-50 rare-gas mass spectrometer with an extraction line capable of heating samples both by resistance heating and CO2 laser is maintained in teh Thermochronology Lab. This instrument is used primarily in 40Ar/39Ar dating. This high resolution (>600), low-background mass (mass 36 <5 x 10-14 cm3 STP, mass spec is capable of measuring all variety of K - bearing geologic material including very young (<1 Ma) and very small samples (<5 mg). Although the focus of this lab is 40Ar/39Ar analysis, all other noble gases (including He) can be analyzed.
