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.

Analysis to screen a material for the presence of brominated flame 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 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.

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.

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. This helps us confirm method suitability and prepare an accurate quote.
