ICP-MS ablation Laser

Inductively Coupled Plasma Source Spectrometry associated with an in-situ laser ablation sampling device.


  • ICP-MS Thermo Element XR spectrometer with magnetic sector and able to operate at low, medium or high mass resolution. This instrument is equipped with a Faraday cage allowing the collection of signals over 12 orders of magnitude.
  • Agilent 7500 quadrupole ICP-MS spectrometer equipped with high sensitivity “cs” optics and reinforced interface pumping.
  • Resonetics M-50E 193nm excimer laser system fully computer-controlled and equipped with an ATL laser with ultra-short pulse duration (<4ns). The impact diameters are adjustable between 3 and 133µm, the ablation frequency from 1 to 100 Hz and the fluence from 2 J/cm2 to 15 J/cm2. This laser ablation system can be coupled with the Agilent 7500, Thermo Element XR or even the Thermo Neptune Plus multicollection ICP-MS.


Example of applications:

The laser system, coupled with the various ICP-MS is dedicated to in-situ analysis. One of the applications is U-Th-Pb geochronology on separate minerals (zircon, monazite, baddeleyite, rutile, sphene, xenotime) or in thin polished slides. It is also suitable for the determination of trace element contents on minerals, magmatic inclusions or any other object of interest requiring high spatial resolution point analysis that can be standardized.
