Composition of natural- and biogas

Quantification of CH4 (methane), CO2 (carbon dioxide), O2 (oxygen), N2 (nitrogen), H2S (hydrogen sulfide), and H2O (water) in natural- and biogas samples with gas chromatography. Additional possibilities to analyze siloxanes (hexamethylcyclotrisiloxane (D3), octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), hexamethyldisiloxane (L2), octamethyltrisiloxane (L3), decamethyltetrasiloxane (L4), dodecamethylpentasiloxane (L5), and trimethylsilanol (SiOH)) as well as ammonia (NH3, using IC).

The base package includes the quantification of CH4, CO2, O2, N2, H2S, and H2O.
