Ultra high precision measurements of 143Nd/144Nd using Xact amplifiers and 1e11 ohm gain resistors

Posted on 23rd October, 2012

The ability to achieve sub 5ppm precision for 143Nd/144Nd is seen as a benchmark for any TIMS system. Such high precision can only be achieved if the mass fractionation correction is accurate and the integrated noise on the detectors is extremely low. In practice Phoenix TIMS systems undergoing factory testing...

Potential for 90Sr measurement on the Phoenix TIMS

Posted on 9th October, 2012

90Sr is a fission product of uranium and plutonium and is expected to be released in a high quantity in a nuclear accident. Sr easily substitutes for Ca and accumulates in bone hence exposure to radioactive Sr represents a significant cancer risk. Additionally, the relatively long half life of 90Sr...
