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.

Determination of total nitrogen content in pyrolysis oil and other liquid, particle-free petroleum samples by oxidative combustion and chemiluminescence detection (ASTM D5762). Results are reported in mg/kg over a measurement range of 40–5000 mg/kg, with a limit of quantification (LOQ) of 0.5 mg/kg. Nitrogen-containing compounds affect downstream upgrading, catalyst performance, and emissions, making nitrogen content a relevant parameter for both process development and quality control. 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.

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.

Determination of total halogen content (F, Cl, Br) in aromatic hydrocarbon matrices such as pyrolysis oil and other petroleum products, where halogen impurities can affect catalyst performance, corrosion risk, and downstream processing. Testing is conducted according to EN 15408, or DIN 51727, with the most suitable method selected based on the sample matrix and expected concentration levels. All methods are based on oxygen combustion followed by detection using ion chromatography or other suitable analytical techniques. The typical reporting range is between 10 and 2000 mg/kg per element. 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.

Bulk density of solid biofuels, such as biochar or wood pellets. The default method is ISO 17828, but DIN 51705 can be followed upon request. The ISO method has two standard measuring containers with a volume of 5 l or 50 l, depending on the particle size of the material: small (<12 mm) with 5L volume and larger with 50L container. The test portion volume must exceed the volume of the measuring container by at least 30%.

Flash point is the lowest temperature at which a liquid generates sufficient vapour to ignite under defined test conditions. It is widely used in hazard communication frameworks because regulatory classification of flammable liquids is based on measured flash point thresholds. Measurlabs offers flash point testing for pyrolysis oil and other petroleum products according to ASTM D93 or EN ISO 3679, depending on the expected flash point of the sample. The application range of ASTM D93 is approximately 40 to 300 °C, while EN ISO 3679 covers approximately -25 to 130 °C.  ASTM D93 is a Pensky-Martens closed cup method commonly used for petroleum products and other liquids, while EN ISO 3679 is a closed cup rapid equilibrium procedure suited to lower flash point materials. Results are reported as a numerical flash point value in °C. To request an offer, please disclose the precise sample matrix and the expected flash point range to enable standard selection. The displayed price applies to small sample sets; larger batches and recurring orders are eligible for discounted pricing.

Analysis conducted according to EN ISO 12185 to determine the density of liquid petroleum-related samples using a laboratory density meter with an oscillating U-tube sensor. ASTM D4052 is available as an alternative method standard. The measurement is suitable for single-phase liquids in the range of 600–1100 kg/m³, including petroleum products, pyrolysis oils, diesel exhaust fluid, vegetable oils, and lubricant oils, provided the sample is liquid, particle-free, homogeneous, or easily filterable. The measurement can be conducted at different temperatures (e.g., 15, 20, or 25 °C). Gasoline and diesel fuel densities, for example, are determined at 15 °C according to the EN 228 and EN 590 standards, respectively. Results are reported as numerical density values in kg/m³ at the selected analysis temperature. To request a quote, please describe your sample matrix, required test temperature, and any applicable specification limits. The displayed price applies to small sample sets, while larger batches and recurring orders are typically eligible for discounted pricing.
