The ICPMS Laboratory

In the ICPMS mass spectrometry lab we analyse isotopic ratios and elemental concentrations in solid matter and solutions. The lab is used primarily for U-Pb and Lu-Hf analysis of zircon as well as trace element analysis of solid matter and solutions, but other types of analyses/samples are possible. The lab has over the years provided analyses of high quality for our own researchers and partners, and for teaching at the Dept. of Geosciences.

Instruments:

The ICPMS lab consist of two inductively coupled plasma mass spectrometry instruments with the following equipment:

  • HR MC-ICPMS, Nu Plasma, from 2004

    • Cetac LSX-213 G2+ laser microprobe

    • Nu Instruments DSN-100 desolvating nebulizer

  • Q-ICPMS; Bruker Aurora Elite M90, from 2013
    • Cetac LSX-213 G2+ laser microprobe
    • Cetac ASX-250 autosampler
    • ESI one FAST sample introduction system

The lab has access to the shared sample preparation facilities.


Description of services:

  • Multicollector MC-ICPMS Sub-laboratory:
    • In-situ uranium-lead dating and lutetium-hafnium isotopic analyses of zircon, as well as lead isotopic analyses of solutions, are done routinely.

    • Analyses of other isotopic ratios in solid matter and solutions, may be possible, but must be discussed and tested to ascertain if it is possible to do the particular type of analysis in the lab.

  • Quadrupole Q-ICPMS Sub-laboratory:

    • In-situ and solution-based elemental concentration analysis is done routinely. However it is necessary to discuss whether our lab can handle the specific  analysis. We need to know the type of mineral, solid matter to be analysed in-situ, the dissolution process, which element (s), type of matrix etc. for solution samples.

ICPMS (inductively coupled plasma mass spectrometry) is an analytical technique capable of ultra-trace detection because of the way it generates ions.

In an ICPMS instrument ionisation is achieved by using argon gas to produce a plasma. This c. 6000-7000 K plasma is capable of ionising most of the elements in the periodic table. The sample is passed through the plasma where it is ionised before it travels through the instrument, to the mass separator,  where unwanted masses are filtered out, and ultimately to the detector.

ICPMS instruments are used in many different methods such as laser ablation uranium-lead dating of zircon where cathodoluminescence images (as seen on the right) can help identify areas of interest – zircon can record multiple growth events which can have different ages, trace and rare earth element concentration determination of solid and solution-based samples, lead isotope characterisation, etc.

The laboratory can by appointment be used for research activities and/or to assist students at the Department of Geosciences.
