ICP-OES measurement package for soil, sludge, or sediment samples. Pre-treatment of the sample with aqua regia decomposition is included in the price. The following elements are quantified using the ICP-OES technique: Element Detection limit (mg/kg d.m.) Ag 0.5 As 0.5 Ba 0.2 Be 0.01 Cd 0.4 Co 0.2 Cr 0.5 Cu 1 Fe 10 Hg 0.2 Li 1 Mn 0.5 Mo 0.4 Ni 1 P 5 Pb 1 Sb 0.5 Sn 1 Sr 0.1 Tl 0.5 V 0.1 Zn 3 The concentrations are expressed in mg/kg d.m. A nutrient measurement package for soil, sludge, or sediment samples is also available. This package includes aqua regia decomposition pretreatment and the measurement of the following elements with the ICP-OES technique: Al, B, Bi, Ca, K, Mg, Na, S, Se, Si, Te, Ti, and Zr. The analysis is also available with an express turnaround time. Ask our experts for more information.

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.

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

This metal screening analysis includes the semi-quantitative determination of 70 elements. The method can be used, for example, to determine the background concentrations of metals in environmental samples or to study the elemental distribution of unknown samples. Screening is also often performed to assess which metals should be analyzed by a quantitative method. The measurement is performed using a high-resolution ICP-MS technique (ICP-SFMS), which can identify very low elemental concentrations. A semi-quantitative determination of the following elements is included: Ag, Al, As, Au, B, Ba, Be, Bi, Br, Ca, Cd, Ce, Co, Cr, Cs, Cu, Dy, Er, Eu, Fe, Ga, Gd, Ge, Hf, Hg, Ho, I, Ir, K, La, Lu, Mg, Mn, Mo, Na, Nb, Nd, Ni, Os, P, Pb, Pd, Pr, Pt, Rb, Re, Rh, Ru, S, Sb, Sc, Se, Si, Sm, Sn, Sr, Ta, Tb, Te, Th, Ti, Tl, Tm, U, V, W, Y, Yb, Zn and Zr. However, please note that some elements may not be determinable due to matrix interference. During this semi-quantitative analysis, the instrument is calibrated for about 30 elements. The rest of the analytes are quantified using sensitivity factors for calibrated elements with similar mass and first ionization potential, considering isotope abundances. Quantitative analysis is also available at an additional price. During this analysis, all elements are calibrated (excluding halogens and Os). Please ask for an offer for this service.
