A laser desorption resonance ionization mass spectrometer for Rb-Sr geochronology: Sr isotope results
We are developing a portable laser desorption resonance ionization mass spectrometer (LDRIMS) for determining the radiometric age of rocks using the 87Rb- 87Sr isotope system, as well as constraining lithologic evolution and measuring chemical compositions. The bench-top prototype has been used to assess the capability of LDRIMS to measure 87Sr/ 86Sr. In this paper, we demonstrate that LDRIMS can measure the isotope ratios of a glass standard with 10 ppm net Sr to a precision of ±0.5% (1σ),...[Show more]
