RESEARCH:

The following techniques and instrument combinations are in use:

• ICP-AES: inductively coupled plasma - atomic emission spectrometry
• GFAAS: graphite furnace - atomic absorption spectrometry
• ICP-MS: inductively coupled plasma-mass spectrometry
• Separation techniques: HPLC, PAGE, CE, IC
• Hyphenation of separation methods and specific atomic detection

Research areas:

• Multi element analysis by ICP-AES or GFAAS
• Analyses of trace and ultra trace elements in e.g.:
• Water systems o Rock samples
• Nutrition
• Biological samples
• Prosthetic materials
• Archeological materials (ceramics, bones, bronze)
• Textiles
• Speciation of metals in different matrices
• Gaseous sample introduction (hydride generation) in ICP-AES or GFAAS
• Hyphenation of separation methods and atomic specific detection
• Investigation of the effects of organic solvents in the Ar-plasma

Projects:

• Trace elements in prosthetic materials and tissues
• Untersuchungen von Metallelementen in menschlichen Organgeweben nach Implantation von orthopädischen Metallimplantaten
• Spurenelementanalysen von Humanknochen aus dem Mittelalter
• Importance of trace elements for textile industry
• Rare Earth Elements in Rock Samples
