Microplastics in biological samples of animal origin

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.

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.

Determination of Be, Ba, Co, Al, Mg, Cu, Li, Mn, Ag, Sn, Ti, V, Zn, Tl, B, Hg, Mo, Fe, Ca, K, U, P, Cd, Na, Cr, Ni, Pb, Sb, As, and Se in water samples with ICP-MS-technique. The sample is homogenized and acidified (HNO3), after which the analysis is performed from the liquid phase. The analysis is suitable for natural waters. If the sample contains a lot of solids or the matrix is significantly different from natural water (for example waste and industrial waters), please contact our testing expert and ask for an offer. 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 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 of gaseous samples using Raman spectroscopy.

Pyrolysis gas chromatography-mass spectrometry (py-GC-MS) analysis to determine the identity of an unknown polymer sample. During the measurement, the sample is instantaneously heated in an inert atmosphere or vacuum. This causes the sample to decompose into smaller molecular fragments which are then analyzed with GC-MS. Different types of polymers can be identified by their unique decomposition products. This includes, but is not limited to: PE, PP, PS, ABS, PMMA, PET, PC, PVC, polyamides, natural & synthetic rubbers, and more. The price includes the basic preparation and analysis of the sample. More extensive sample preparation is subject to additional costs.
