Identification of chemical groups with FTIR (solid samples)

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.

Determination of the total organic fluorine (TOF) content in combustible materials using combustion ion chromatography (CIC). By default, TOF is analyzed as total fluorine (TF). If required, total inorganic fluorine (TIF) can be measured as well, and TOF calculated as the difference between TF and TIF. TOF analysis gives information about the total amount of organic fluorinated compounds. It can also be used to evaluate the presence of per- and polyfluoroalkyl substances (PFAS) in the material, even though individual PFAS compounds can't be analyzed with this method. The analysis is suitable for many different materials. Please describe the sample in detail when requesting an offer to help us prepare a quote quickly.

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.

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. Do not hesitate to ask for a quote.

Determination of biobased carbon content in plastics and plastic additives by accelerator mass spectrometry (AMS) according to ISO 16620-2. The method applies to monomers, polymers, polymer resins, plasticizers, and additives containing any combination of biobased and fossil-based carbon. Results are reported as biobased carbon content (%) relative to total carbon (TC), derived from the measured percent modern carbon (pMC) value. The data can be used to support biobased carbon content declarations under ISO 16620-5. ISO 16620-2 is almost identical to the European EN 16640 standard and technically similar to ASTM D6866. All three are based on the radiocarbon (¹⁴C) method, which allows unambiguous quantification of biobased carbon content without prior knowledge of the production process. However, ASTM D6866 is broader in scope, as it applies to a wide range of solid, liquid, and gaseous matrices, while ISO 16620-2 is specific to plastics. The displayed price applies to non-volatile samples. If your sample is volatile, please discuss the testing options with our experts. Please also note that we cannot accept samples that contain artificial carbon-12, carbon-13, or carbon-14 isotopes because they will damage the equipment.

Measurement of biogenic or biobased carbon in a material or product as a percentage of total carbon or total organic carbon. ASTM D6866 outlines two ways of expressing the proportion of material that originates from renewable resources. Biogenic carbon content indicates the proportion of total carbon (TC) originating from renewable resources. Alternatively, inorganic carbon can be removed before testing, and the result is then expressed in relation to total organic carbon (TOC), giving the biobased carbon content. An additional cost applies to the removal of inorganic carbon. Note! The results obtained for gaseous emissions should always be expressed as "biogenic carbon content" because the initial step of converting carbon to gaseous CO2 cannot be done when the carbon is already in gaseous form. The displayed price range applies to non-hazardous, non-volatile samples. If your sample is volatile or classified as Dangerous Goods, please discuss the suitability of your sample type with our experts. Please also note that we cannot accept samples that contain artificial carbon-12, carbon-13, or carbon-14 isotopes because they will cause damage to the equipment. ASTM D6866 tests do not directly reveal how much of the sample's total weight originates from renewable sources. This can be estimated, however, by combining data on biobased carbon content with information on the total carbon content of the product. One common application of this measurement is determining the biomass fraction of CO2 emissions for the EU Emissions Trading System (ETS), as required by the Monitoring and Reporting Regulation (MRR). For this purpose, testing is relevant to municipal waste incineration plants and industrial plants that use mixed fuels.

Determination of biobased carbon content by accelerator mass spectrometry (AMS) or liquid scintillation counting (LSC) according to EN 16640, a horizontal European standard applicable to any product containing carbon — including paints, adhesives, solvents, detergents, composites, and raw materials. Results are reported as biobased carbon content (%) relative to total carbon (TC) of the sample. EN 16640 is the default standard for substantiating biobased carbon content claims for non-plastic products intended for the EU market. It was developed by CEN/TC 411 as part of a suite of horizontal standards for biobased products, and is technically almost identical to ISO 16620-2, although the latter applies specifically to plastic products and additives. Any other differences between the two reflect editorial conventions of the respective standardization bodies rather than methodological differences.  Both standards are also technically similar to ASTM D6866, which follows the same radiocarbon principle. The displayed price applies to non-volatile samples. If your sample is volatile, please discuss the suitability of your sample type with our experts. Samples containing artificially enriched carbon isotopes (¹²C, ¹³C, or ¹⁴C) cannot be analyzed, as these will damage the instrument.

Raman spectroscopy is a non-destructive chemical analysis technique used for the identification of chemical components in a sample. This analysis is suitable for inorganic and organic liquid samples.
