We offer customizable analysis packages to determine the composition and contamination level of sediment samples according to the EU Water Framework Directive, Environmental Quality Standards Directive, and national environmental monitoring regulations. Our services cover standard physical and chemical quality parameters, as well as extensive pollutant screening. One of our basic analysis packages includes the following determinations: Dry matter, Heavy metals (As, Cd, Cu, Hg, Cr, Pb, Ni, Zn), Organotin compounds (tributyltin and triphenyltin), Dioxins and furans (PCDD/PCDF), PCB compounds, PAH compounds, Clay content and grain size distribution (11 fractions), Loss on ignition (LOI), Hydrocarbons C10–C40, Total nitrogen, Nitrate and nitrate nitrogen, Nitrite and nitrite nitrogen, Ammonium nitrogen, Total phosphorus, Soluble phosphorus, Total organic carbon (TOC). Other parameters can be added to the analysis package upon request, with examples including PFAS compounds, additional metals, and microplastics. Similarly, unnecessary parameters can be removed. We can also help organize the sampling through our partner, an environmental consultancy with 20+ years of experience in sediment sampling in the Baltic Sea region. However, this service is not included in the analysis price. The pricing of the analysis depends on the selected parameters and the number of samples delivered at once. The price range shown here is the estimated price for the analysis package presented above. Please contact our experts for more information and a quote customized to your analysis project.

Karl Fischer titration is a classic titration method in chemical analysis that uses coulometric or volumetric titration to determine trace amounts of water in a sample. Please note that aldehydes and/or ketones in the sample severely disturb the KF titration. If the sample material includes these substances, please contact us before making an order.

Determination of total organic carbon (TOC) content of water samples. The results of the analysis will be reported in mg/l.

Testing for harmful substances in metal jewelry parts according to the requirements of REACH Regulation (EC) No 1907/2006. The test package includes the following tests: Transfer of nickel from jewelry to the human body. Limit value for first-time piercing jewelry 0.2 µg/cm²/week. For other jewelry, the limit is 0.5 µg/cm²/week., Cadmium (concentration test, limit value 0.01% by weight), Lead (concentration test, limit value 0.05% by weight). NOTE: Price is applicable for single jewelry parts (for example earring hooks etc.) and pricing is based on small sample sets. Discount is provided if the number of samples is high. Please ask for an offer from our expert if the tested product includes multiple parts or materials or if you are planning to deliver a bigger sample set at once.
