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 and 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.

Our targeted PFAS analysis options for wastewater, process water, and other highly contaminated water samples include the following:  In-house method based on EPA 1633 with 49 target compounds and a reporting limit of 1-2 ng/l. The analysis is suitable for both treated and untreated wastewater and is often used when evaluating the PFAS-removal efficiency of the treatment process. , Official EPA 1633 method that targets the 40 compounds specified in the standard. The price for this measurement is slightly higher than that for the in-house method., In-house method based on EPA 533 or ISO 21675 with 57 target compounds and a reporting limit of 0.2 ng/l for most compounds. . Please note that the reporting limits can be higher for extremely contaminated samples. Full target compound lists for each method are available upon request. When requesting an offer, please describe the expected contamination level of your samples and any specific requirements regarding testing standards or target compounds.

The sample is homogenized and acidified (HNO3), after which the analysis is performed from the liquid phase. The displayed price applies to natural waters. If the sample contains a lot of solids or the matrix is significantly different from natural water (for example, wastewater and industrial waters), additional steps may be needed, and this will be reflected in the price. The concentration of each element is reported in µg/l.

Determination of carbon, hydrogen, nitrogen, sulfur, and oxygen content of an organic sample. CHNS analysis (”LECO analysis”) is performed using a flash combustion method, where the sample is combusted under 25 kPa of O2 at an elevated temperature (1000 °C), followed by gas chromatography separation and detection using a thermal conductivity detector. Oxygen is analyzed by reduction on granulated carbon at 1480 °C, utilizing high-temperature thermal decomposition and conversion of oxygen into carbon monoxide before gas chromatography separation and detection with a thermal conductivity detector. The sample can be either solid or liquid, but water in the sample affects the results. In the case of aqueous samples, it is possible to dry the sample before analysis. The displayed price by includes the full CHNOS package with two parallel measurements and applies to conventional organic samples. The results are reported as wt-% of the initial sample. The ash, drying and dry loss measurements will increase the minimum required sample material need to 300 mg. The analysis gives the total carbon, hydrogen, nitrogen, sulfur, and oxygen content of the material, but it does not identify any chemical structures. The measurement can be combined with other methods, such as GC-MS, 1H, and 13C NMR, to perform substance structure identification. Analysis can be split into the following packages: CHN, O, and S.
