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 price includes two parallel measurements. 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. Possible element packages: O, CHNS, and CHNOS.

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.

Total oxidizable precursors (TOP) assay analysis can be used when estimating the presence of PFAS precursors and intermediates by oxidizing them into stable end-products. The analysis can be combined with traditional PFAS analysis methods to obtain additional information. The analysis is suitable for different matrices, for example, water and fire-fighting foams. Contact the method expert for more information.

Determination of amino acids from waste water. The analysis includes the determination of the following amino acids: Alanine, Arginine, Asparagine, Aspartate, Citrulline, Cystine/Cysteine*, Glutamate, Glutamine, Glycine, Histidine, Hydroxyproline, Isoleucine, Leucine, Lysine, Methionine, Ornithine, Phenylalanine, Proline, Serine, Taurine, Threonine, Tryptophane, Tyrosine, Valine.

Analysis to screen a material for the presence of brominated fire retardants (BFRs), including polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs). The test is performed with a pyrolysis gas-chromatography mass spectrometer (py-GC-MS) according to the ISO 7270-1 standard. The sample is pyrolyzed, which is followed by separation and identification with GC-MS. The obtained pyrogram is then compared to a blank sample that does not contain any brominated fire retardants. We also offer the analysis for electrotechnical products as per IEC 62321-6. Please ask our experts for more information about this option.

The chemical oxygen demand (COD) of pulp process liquid is measured according to the ISO 6060 standard to evaluate the environmental burden of the water sample. The sample must be kept at a temperature <5° C and analyzed within 5 days of sampling.

Volumetric (static) or dynamic (pulse) chemisorption analysis by CO or H2. The method is mainly used to determine catalyst activity and active sites. When coupled with TPX (temperature programmed experiments, TPO, TPR, TPD), this method can give information about adsorbed species and surface species. Chemisorption can also be conducted with other reactive gases, please contact us for more information.
