The trace analysis platform (TAP) at the Department of Chemistry, Umeå University aims to provide state-of-the-art equipment, instrumentation, user training and support for trace analysis of small molecules in complex matrices, such as environmental and biological samples.
It supports qualitative and quantitative analysis of metals, organic compounds, organo-metallic compounds, and isotope ratios of trace gases. There is support for both total concentrations and speciation for metals and organo-metallic compounds.
The platform primarily provides access to instrumentation, but can also provide analytical services and operator training. The services may include: design of experiments, sample preparation, instrumental analysis and interpretation of data.
Service is provided at three different levels:
Seed projects (a few samples)
Small projects (10s of samples)
Projects and long-term service (100s of samples)

The equipment that forms the foundation of the platform is supporting work in the following areas:
Trace element analysis (metals, phosphorus, sulfur, chlorine and bromine).
Speciation (Hg, Sn and As compounds)
Isotope ratio determinations
Protein-metal complexes and interactions
Trace analysis of persistent organic pollutants (POPs)
Multi-residue analysis of pharmaceuticals
Indoor air pollutants
Identification of unknowns
Stable isotope tracer experiments
Effect-directed fractionation and analysis
The platform shall continue to support research within these areas, but shall also provide support to researchers working in other areas that are in need for trace analysis of small molecules.
