Description

The Isotope Geochemistry Labs are equipped with a clean room facility (including several low-blank chemistry laboratories (class 100), sample preparation and ion-exchange chromatography, a set up for isotope systems: Pb, U-Pb, Rb-Sr, Sm-Nd as well as B and Li isotopes), two thermal ionization mass-spectrometers (TIMS) and a multi-collector mass-spectrometer with inductively coupled plasma source (MC-ICP-MS).

Instruments

ION CHROMATOGRAPHS are recorders that are used in chromatography; a form of high pressure liquid chromatography using conductivity detectors where a combination of weak ionic solvents are used to separate anions and cations of a solution, with the contribution of the solvent to conductivity suppressed just prior to detection; measures anions such as sulfate, nitrate, and chloride in hydrometers.

IC - Ion Chromatograph
Clean Room Facility
The Multicollector Inductively Coupled Plasma Mass Spectrometry (MCICPMS) spectrometer is a double focusing instrument that provides high precision and accurate isotope ratio determinations, coupled with flexibility and ease of use.

Chromatography in which separation is based mainly on differences in the ion-exchange affinities of the sample components. (Source: IUPAC; https://doi.org/10.1515/pac-2017-0111) (Source: Global Change Master Directory (GCMD). 2023. GCMD Keywords, Version 16.3 [...] )

Mass spectrograph based on a double-focusing magnetic analyzer that spatially disperses ions of different m/z values on to an array of Faraday cup detectors, generally used with inductively coupled plasma ion sources for isotopic composition measurements.
