Chemical and biological analyses

Umeå Marine Sciences Centre (UMF) has extensive experience in marine sampling, participate in international calibrations and specialise in biology and chemistry of brackish water. We do analyses for government agency and universities.

Every year, many chemical and biological analyses are performed at Umeå Marine Sciences Center (UMF), on assignment of universities and governmental authorities. We have a long tradition of analysing marine samples, participate in international calibration programmes, and are specialised in brackish water samples. Umeå Marine Sciences Centre is accredited by Swedac for most of the methods we use.


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 14C method is used to determine the phytoplankton primary production. Bacteria growth is determined by using the 3H-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 analyses are commissioned by researchers and governmental authorities. UMSC works actively to assure the quality of the marine-chemical analyses, e g by taking part in the quality assurance programme Quasimeme.

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

Accreditation

Most of the analyses carried out at UMF are accredited by Swedac (accreditation number 1808).

The accredited work is done in four specialised laboratories, to which only authorised personnel have access. The equipment used for these analyses requires special education, and is only used by authorised personnel.
