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.

Diene value analysis for pyrolysis oil to determine the concentration of reactive diene compounds that can accelerate polymerization and gum formation, affecting product stability and downstream process performance. The analysis is performed in accordance with the UOP 326 standard, which is widely applied to diene value determination in petroleum- and pyrolysis-derived oil matrices. The sample is reacted with maleic anhydride, and the diene content is determined by back-titration of the unreacted anhydride. Results are reported in g/100 g. Typical applications include process control, feedstock qualification, and specification setting prior to hydrotreatment, blending, or other upgrading steps. The results can also be used to compare pyrolysis conditions and monitor batch-to-batch variation. The displayed price applies to small sample sets. Please specify the number of samples when requesting a quote, as volume discounts are available for larger batches.

Determination of the dynamic shear viscosity using a rotary rheometer. The displayed price includes a shear rate ramp test at a specified temperature. Please specify the following upon ordering the test: desired testing temperature (max. 200 °C), desired shear rate range (from 0,1 s^-1 to 100 s^-1). The set-up configuration of the rheometer can be chosen based on the sample type (the most common options are parallel plate and cone-and-plate). Do not hesitate to ask for a quote for a custom viscosity testing program. For example: temperatures from -20 to 600 °C, and shear rate ranges from 0,01 to 1,000 s^-1 are possible, as well as rotational and oscillatory measurements, time and temperature sweeps, etc.

Determination of total chemically bound oxygen in pyrolysis oil, gasoline, and other petroleum products. The analysis is conducted using a reductive pyrolysis method specified in the ASTM D5622 standard, and the results are reported as the mass percent (%) of oxygen in the sample. Typical applications of the test include refinery and terminal quality control, oxygenate blending verification, and regulatory compliance testing. Applicable limits include 2.7–3.7% (m/m) under EN 228 and 2.0–2.7 wt% under US EPA requirements. The displayed price applies to small sample sets, while larger batches and recurring orders are eligible for discounted pricing. Please request an offer from our experts using the form below.

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.
