Marine analyses

Research infrastructure Umeå Marine Sciences Centre (UMF) analyzes marine samples, participates in international calibrations and is specialized in brackish water biology and chemistry. Analyses are performed on the request of government agencies and universities, supporting research and environmental monitoring. The analyses are accredited by Swedac.

Biological analyses

The analyses include species identification, biovolume and primary production for phytoplankton, bacteria growth and bacteria concentration, picocyanobacteria concentration, abundance and biomass for phytoplankton and soft bottom fauna. The C14 method is used to determine the phytoplankton primary production. Bacteria growth is determined by using the H3-tritium method.

Chemical analyses

About 10 000 chemical analyses are performed at UMF every year. Besides water, sediment and other solid samples can be analysed. 

The following instrumentation is used to determine carbon, nitrogen and phosphorus in various sample types:

  • Nutrients - QuAAtro Autoanalyzer
  • Dissolved and total organic carbon in water - TOC Instrument
  • Chlorophyll and humic substances - Spectrofluorometer
  • Salinity - Bench salinometer
  • Alkalinity - Metrohm titrator

Calibration and accreditation

UMF regularly takes part in international quality assurance programmes, for example the European Quasimeme-programme.

UMF is accredited by Swedac for biological and chemical analyses. Expert staff perform the accredited analyses, and specialized laboratories are used to which only authorized personnel have access.
