Project Summary (2000-2005)

The Trace Metals Analysis Core conducts state-of-the-art trace and ultratrace analyses on both metals and their species. The central feature of the core is a magnetic sector High Resolution Inductively Coupled Plasma Mass Spectrometer (HR-ICPMS) which provides unsurpassed detection limits and interference free accurate analyses while allowing high sample throughput. Additionally, ICPMS is capable of precise isotope ratio measurements which allows the application of stable isotope tracer experiments as well as highly accurate isotope dilution analyses for elements with more than one stable isotope. Combined with chromatographic techniques HR-ICPMS represents the most sensitive element-specific detection technique for different metal species.
