Developing state-of-the-art analytical techniques for high-precision U-Pb dating

Performance of the IsotopX PHOENIX thermal ionisation mass spectrometer for high-precision U-Pb geochronology, since 2016 The new mass spectrometer is equipped with a highly sensitive and linear Daly ion counting system and high-resistance 10E12 Ohm Faraday cups for low-level multicollection of small Pb and U ion beams. It is operational since September 2016 and delivers U-Pb dates of 0.02 to 0.01% internal precision in 206Pb/238U age.
