Content

Methods of ion generation, mass separation and ion detection :
- Thermal ionisation and TIMS
- Secondary ion emission and SIMS
- Inductively coupled plasma ionisation and ICPMS

Construction of the mass spectrometer with an ICP ion source :
- The plasma torch, RF generators, interface
- Ion optics
- Quadrupole, sector-field, time-of-flight mass discriminators, resolution
- Detectors

Methods of sample introduction for ICP-MS :
- Nebulisers and Desolvators
- Solid-state and Excimer Lasers

Mass spectrum, calibration and data reduction in ICP-MS :
- Mass spectrums, resolution, abundance sensitivity
- Spectral overlaps and their handling
- Signal structure, uncertainties, detection limits
- Semi-quantitative elemental analysis
- Quantitative elemental analysis, external / internal standardisation
- Isotope ratios, (Th)-U-Pb geochronology

The course is accompanied by practical exercises with two instruments :
- Agilent 7700x quadrupole ICP-MS & GeoLas 200M laser ablation system
- Element XR sector field ICP-MS & UP-193 FX laser ablation system
