Correction of multi-collector-ICP-MS instrumental biases in high-precision uranium-thorium chronology
We present a method for the calibration of in-house thorium isotope standards for use in U-Th chronology, along with an assessment of instrumental biases on the Nu Plasma multi-collector inductively-coupled-plasma mass spectrometer. Uranium and thorium mass fractionation is found to be very strongly...
