Inorganic Chemistry Laboratory
We carry analyses of water, soil and sediments and offer standard and well-documented methods for research and advisory projects.
Inorganic chemistry laboratory is research laboratory equipped with a wide range of instruments to measure inorganic substances and dissolved organic carbon in water (soil, surface and groundwater) or extractions from soil and sediments. Furthermore, we prepare soil and sediment samples for X-ray analysis.
Handling of samples may be done in ordinary laboratory conditions or in controlled atmosphere, e.g.
N. 2 or Ar Instruments
The key instruments in the laboratory are:
Ion chromatography equipment with three different detection units (conductivity, amperometry and spectrometry)
Atomic absorption spectrophotometer (AAS)
Total organic C and total N analyzers
Flow injection analyzer (FIA)
Automated titration system for analysis of water samples and extractions
Instrument for analysis of surface area and pore size of soil and sediment samples.
We also have equipment for preparing of soil and sediment samples for X-ray analysis.
