Services in the Analytical lab

In order to assess the possible applications of different biomasses, the chemical composition and fuel properties of liquid fuels, solid biofuels, biogas substrates, by-products and residues as well as their conversion products such as ashes, filter dusts and process waters are investigated in the DBFZ's analytical laboratory.

The analysis is carried out both according to current standards and according to problem-oriented method development or adaptation. With the existing equipment the following parameters can be determined: pellet density, bulk density, particle size distribution, fines, abrasion resistance, fuel/heat value, water content, volatile content, carbon content (fixed, elemental and organic), CHNS composition, ash content, element composition with regard to main and trace elements, total contents of sulphur and chlorine as well as concentrations of elutable components, density, viscosity, refractive index, flash point, copper corrosion degree, acid and saponification number for glycerine as well as pH value. Polycyclic aromatic hydrocarbons (PAHs), fatty acid methyl esters (FAMEs) and phenols can be identified and quantified by GC analysis and the concentrations of sugars and furan derivatives can be determined by HPLC. In the future, a method for the determination of volatile organic hydrocarbons (BTEX) by GC will be established.
