Aanbieding 1 met studiegidsnummer 4023293DNR voor alle studenten in het 2e semester met een inleidend master niveau.
In this course, the students first obtain insight into the sources of natural variation in the isotopic composition of the elements. Subsequently, they are familiarized with the basic principles of the most important types of mass spectrometers and laser spectrometers deployed for isotope ratio measurement. The capabilities of isotopic analysis are illustrated via real-life applications from various research fields. This course aims at providing the student with a quite profound insight into the techniques that are deployed in the context described above, their application areas and the capabilities and limitations of isotopic analysis
Contents
· The isotopic composition of the elements: natural abundance, isotope fractionation and notation for “light” & “non-traditional” stable isotopes
· Thermal ionization mass spectrometry (TIMS)
· Multi-collector ICP – mass spectrometry (MC-ICP-MS)
· Accelerator mass spectrometry (AMS, for 14C-dating & other applications)
· Principles of measurement of light stable isotopes via isotope ratio mass spectrometry (IRMS)
· Compound-specific stable isotope analysis via GC- and HPLC-IRMS
· Laser-based spectroscopy for light element stable isotope analysis
· Isotope ratio applications: geochronological dating, provenance determination, nuclear applications, stable isotopic tracer experiments, applications based on natural isotope fractionation effects, source identification and biodegradation of pollutants, 15N tracing studies for N biogeochemistry, stable isotope probing and use of biomarkers (e.g., erosion and nitrate source apportionment and paleo-climatology), water isotopes for eco-hydrological studies.
Course notes will be provided via UFORA
