Microanalysis of Pb isotope ratios of low-Pb glass samples by femtosecond laser ablation-multiple ion counter-ICP-mass spectrometry (fsLA-MIC-ICP-MS)

We report high-resolution in situ Pb isotope analysis (207Pb/206Pb and 208Pb/206Pb ratios) by femtosecond laser ablation-multiple ion counter-inductively coupled plasma-mass spectrometry (fsLA-MIC-ICP-MS) for low-Pb geological reference glasses. Pb isotope analysis was realized using a multiple ion counter (MIC) and a modified inductively coupled plasma (ICP) ion interface to improve the signal-to-noise ratio and instrumental sensitivity, respectively. Use of femtosecond deep-UV (200 nm) laser ablation enhanced the sampling efficiency of the small amount of glass.
