Fuel Technology Laboratory
The fuel technological laboratory deals with the analysis of gaseous fuels. In particular, the composition of natural gas, biogas or CNG is examined using gas chromatography. Further analyses for the quantification of gas impurities (i. a. sulfur compounds) are also performed. There are also modern analyzers available (e. g. calorimeters, gas chromatograph and various devices for determining the elemental composition) for the analysis of liquid and solid substances. Special customer requests such as the establishment and management of specific experimental apparatus can be performed by the skilled laboratory personnel.

A selection of sampling and methods of the fuel-technical laboratory are accredited (D-PL-12098-01-01).

Gas Chromatography
Here the focus is mainly on the analysis of the composition of natural gas, CNG (According to DIN EN ISO 6975) or biogas using specific detectors. Calculation of fuel properties of the gas composition in accordance with DIN EN ISO 6976 and the determination of higher hydrocarbons up to C40 by FID screening and implementation of GC-MS analyzes for identifying unknown substance mixtures are also carried out.

Sulfur analysis
The activities in this department include the analysis for the quantification of gas impurities, in particular the determination of sulfur in natural gas and CNG according to DIN EN ISO 20846 and the determination of total sulfur and individual sulfur components in gaseous, liquid and solid fuels using specific standard procedures.
