AbstractA high-precision MIC-ID-TIMS (multiple ion counting-isotope dilution-thermal ionization mass spectrometry Pb isotope ratio measurement method (using Pb-205 as spike) with a TRITON Plus TIMS, which is equipped with a Pb-205-Pb MIC array, using a two-line multi-dynamic data collection method, was thoroughly re-set and re-evaluated, based on our previous work.(1) After some vital modifications, better than 0.01% RSE internal precision on Pb-207/Pb-206 for a Pb-205-spiked NIST981 with similar to 50 pg of Ph load was achieved with a measurement time of about 100 min. This is more precise compared to the traditional isotopic measurement method for the Pb-205-spiked Pb, using a single secondary electron multiplier (SEM) with five peak jumps, provided with similar ion beam intensities and measurement time. The external precision on Pb-207/Pb-206 was better than 0.1% (2RSD, n = 24), which is much better than that achieved by the static MIC method as previously reported(1,2). The present work indicates that the Ph-205-Ph MIC array of the TRITON Plus TIMS can be successfully used for zircon ID-TIMS U-Pb dating with high precision, particularly is useful for samples containing extremely small amounts of Pb (down to several pico-grams).
