Diesel exhaust fluid (DEF) is an additive used in diesel-powered vehicles to help the catalytic reduction of nitrous oxides. Thus, the use of AdBlue and other exhaustive fluids improves ambient air quality. DEF testing package according to ISO 22241:2019 includes the measurements listed below: Urea content (ISO 22241-2C), Density at 20 °C (EN ISO 12185) , Refractive index at 20 °C (ISO 22241-2C), Alkalinity as NH₃ (ISO 22241-2D), Biuret (ISO 22241-2E), Aldehydes (ISO 22241-2F), Insoluble matter (ISO 22241-2G), Phosphate (ISO 22241-2H), Determination of Al, Ca, Cr, Cu, Fe, K, Mg, Na, Ni, and Zn content (ISO 22241-2I).

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.

The bromine index indicates the amount of bromine-reactive unsaturated compounds in petroleum products and is used as a measure of olefinic reactivity and product stability. This analysis is primarily intended for pyrolysis oils and is performed according to DIN 51774-1, which determines bromine-reactive content by titrimetric measurement.  Results are reported in g/100 g. Samples must be liquid, homogeneous and particle-free, or easily filterable. The displayed price applies to small sample sets; larger batches and recurring orders are typically eligible for volume discounts.

Measurement of the refractive index of powder samples with the Becke line microscopic method. The analysis is suitable for transparent crystalline materials with a particle size larger than 40 μm. Measurements are performed at a 589.3 nm wavelength. Refractive index values from approximately 1.40 to 1.70 are reported with a precision of up to two significant digits. Please note that the method does not directly determine the particle's absorption coefficient (imaginary value).

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.

In this pour point analysis for pyrolysis oils and other petroleum products, the sample is cooled under controlled conditions and inspected at defined temperature intervals to determine the lowest temperature (in °C) at which it still flows. The pour point is an important parameter for low-temperature handling and storage performance. The appropriate method (ASTM D97 or EN ISO 3106) is selected based on sample properties, with ranges of −90 to 50 °C. The displayed price applies to small sample sets; larger batches and recurring orders are typically eligible for volume discounts.

Determination of gross and net calorific value in pyrolysis oil, petroleum products, and related combustible materials by bomb calorimetry according to ASTM D240, ASTM D4809, or EN ISO 18125. The sample is combusted in a calibrated bomb calorimeter, and the calorific value is calculated from the measured temperature rise. Results are reported in kJ/kg. The price includes the determination of all parameters required for gross and net calorific value calculation: C/H/N (DIN 51732 or ASTM D5291), S (ASTM D4239), ash at 815 °C (DIN 51719), moisture (DIN 51718), and calculated O content. Please disclose the number of samples when requesting an offer, as large batches and recurring orders are eligible for volume discounts.
