Lehrinhalt

Introduction into mass spectrometric methods for isotopic and trace elemental analysis

Basic background and fundamentals of mass spectrometry:
Ionisation sources
Interface and ion optics
Ion separation
Ion detection
Vacuum technology

Measurement related aspects:
Interferences
Mass resolution
Senstivity, abundance sensitivity
Mass fractionation, mass-dependent vs mass-independent fractionation, instrumental isotopic fractionation

Measurement strategies
Quantification/isotope ratios analysis
Metrology and Mass spectrometry (general terminology, SI-units, certified reference materials, etc.)

Sample introduction systems, hyphenated techqiues (e.g. laser ablation)

Short introduction into fields of application
(e.g. geology/geochemistry, biology, life sciences, material science)

Inhaltliche Voraussetzungen (erwartete Kenntnisse)

Basic background in chemistry and analytical chemistry (771107 und 771108 or equivalent)

Lehrziel

The lecture covers state-of-the-art knowledge about methods of (ultra)trace elemental and isotopic analysis along with benefits and limitations of modern mass spectrometric techniques to address analytical questions within various scientific research fields (e.g. geology, environmental science, archaeology, food science).

After completion of the course the students will have a comprehensive knowledge about the use and application of methods along with an overview of the methods available (limits and potentials). They are able to decide on the most appropriate approach for specific research questions in the field of ecosystem research. They have the proper tools for data reduction when applying quantitatiove or isotopic measurements.
