The ICP-MS technique provides information on the concentrations of metals in a sample. This analysis package for solvents includes the following elements: Element Detection limit (mg/kg) Hf 0.0001 Hg 0.0001 Pb 0.0001 U 0.0001 Ga 0.0005 In 0.0005 Rb 0.0005 Ag 0.001 Cd 0.001 Co 0.001 Cs 0.001 Mn 0.001 Mo 0.001 Nb 0.001 Sb 0.001 Sn 0.001 Ti 0.001 Tl 0.001 Te 0.005 V 0.005 As 0.01 B 0.01 Ba 0.01 Be 0.01 Bi 0.01 Cr 0.01 Cu 0.01 Fe 0.01 Li 0.01 Ni 0.01 Se 0.01 Sr 0.01 Zr 0.01 Zn 0.05 Al 0.1 Mg 0.1 P 0.5 Si 0.5 Ca 1 K 1 Na 1 The concentrations are reported in mg/kg or µg/L for each measured element. Please send the safety data sheet (SDS) together with the samples.

Determination of the concentrations of Co, Si, P, S, B, and Na in solid chemicals. This method is meant for chemicals like Co(NO3)2. The results include the concentration of the main component (Co) and the concentrations of selected impurities.

Rutherford Backscattering Spectrometry (RBS) can be used to measure the composition of solid samples quantitatively at the surface as well as depth profiling. RBS is used for the analysis of heavy elements and can be combined with ToF-ERDA when lighter elements also need to be analyzed. Elements with similar mass can be difficult to differentiate.

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.

Qualitative identification of chemical groups in solid samples by Attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FTIR). Results will be delivered as an FTIR spectrum. In addition, a comparison to an FTIR library will be provided. The method is not quantitative, but it can be used to identify the main chemical components of the sample.

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 (1,000 °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 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 addition of ash, drying, and dry loss measurements will increase the minimum required sample material 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.

Analysis of gaseous samples using Raman spectroscopy.

Analysis package for black liquor and pulp mill process liquids, covering the following parameters: Parameter Method Dry matter content SCAN-N 22 Carbonate SCAN-N 32 Dissolved calcium (Ca) In-house Sodium (Na) SCAN-N 38 Results are reported in mg/kg dry basis or mg/L. Please note that a sample destruction fee will be applied to smelly or otherwise hazardous samples. The displayed price applies to small sample sets; large batches are eligible for discounts.

We offer several accredited methods for determining the total fluorine (TF) content of combustible materials: EN 14582, based on combustion ion chromatography (CIC). The method is recommended by the Nordic Council of Ministers as a quick and powerful total fluorine screening technique., EN 15408 using oxygen bomb combustion treatment followed by ion chromatography (IC). This method can be applied to plastic sheets and granules, and it is also possible to determine the total content of S, Cl, and Br., ASTM D7359-23, based on oxidative pyrohydrolytic combustion, followed by CIC.. The most suitable method is typically selected based on the sample matrix. However, please let us know if you wish a specific standard to be followed. Sample preparation (air drying and milling of the sample to particles <1 mm) is included in the displayed price. This analysis is commonly used to evaluate packaging materials' compliance with the PFAS restriction outlined in the new EU Packaging and Packaging Waste Regulation (PPWR). If TF content does not exceed 50 mg/kg (ppm), the material can be considered compliant without further testing.

This analysis provides quantitative information about the crystalline and amorphous phases within your sample using high-resolution synchrotron X-ray diffraction (XRD). A standard analysis includes: Quantification of crystalline phases as weight percentages, Quantification of the total amorphous content, High-resolution powder diffraction data and the resulting diffractogram, A comprehensive test report detailing the findings. For more advanced needs, we also offer total scattering/pair distribution function (PDF) analysis to reveal the local atomic structure in amorphous or nano-structured materials.
