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: Ag, As, Ba, Be, Cd, Co, Cr, Cu, Fe, Hg, Li, Mn, Mo, Ni, P, Pb, Sb, Sn, Sr, Tl, V, Zn. The analysis is also available with an express turnaround time. Ask our experts for more information.

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. If jewelry includes multiple parts (for example, earrings back part, needle and swinging part), all parts on the sample must be tested, and the price of the analysis is per part. 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.

ICP-SFMS measurement package for liquid chemicals and pure reagents. The analysis includes the measurement of the following elements using the high-resolution ICP-SFMS technique: Element Detection limit (µg/L) Al 0.1 As 0.01 B 2 Ba 0.002 Ca 1 Cd 0.001 Co 0.002 Cr 0.01 Cu 0.2 Fe 20 Hg 0.02 K 2 Mg 0.5 Mn 0.01 Mo 0.04 Na 2 Ni 0.01 P 0.3 Pb 0.01 S 2 Si 5 Sr 0.003 Zn 0.05 The listed limits of determination are the lowest achievable, and they might change depending on the sample matrix and the required pretreatment. Results are reported in µg/l for each measured element. The analysis is also available with express delivery - request an offer from our expert.
