As part of the Radiopurity Service the LSC holds an Inductive Coupled Plasma Mass Spectrometry (ICP-MS) facility.
The ICP-MS facility is mainly in charge of the quantitative analysis of 238U and 232Th contamination of the materials to be used in the construction of the experiments.
The facility is currently in development to perform measurements of 40K contamination.
The ICP-MS is capable of measuring a mass range of 2-290 amu.
The detection limit is ~10-14 g/g which corresponds to an activity of ~10-3 mBq/kg in the case of 238U.
