Gas chromatograph for the analysis of hydrocarbons.
Colorimeter for the measurement H2S.
Chemisorption for the characterization of heterogeneous catalysts.

Gas chromatographic analysis methods combined with detectors like TCD (thermal conductivity detector), FID (flame ionization detector) as well as PFPD (pulsed flame photometric detector) and MS (mass spectrometer) are applied for qualitative and quantitative analyses of permanent gases, hydrocarbons and sulfur compounds. Gaseous and liquid samples can be analyzed offline as well as online by coupling of the GC with different lab plants.

For the continuous analysis of gas concentrations in plants and systems, analyzers with NDIR (nondispersive infrared absorption), TCD (thermal conductivity detector), FID (flame ionization detector), CLD (chemiluminescence detector) as well as Micro-GCs can be applied.

Heterogeneous catalysts can be characterized by several methods available at the institute (BET, FESEM, TEM, XRD,…). This allows the correlation of experimental results on catalytic activity with the catalyst properties.
