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.

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.
