GC Testing

GeoConsult's Gas composition testing utilizes micro Gas Chromatography (micro GC). It gives precise gas analysis in a very quick time period.

Gas composition analysis is carried out in GeoConsult's coal seam gas laboratory.

General Gas Analysis Geoconsult's general gas analysis includes analysis of the following components. This analysis also includes calculation of air free results.

Component

• Helium
• Hydrogen
• Oxygen
• Nitrogen
• Methane
• Carbon Monoxide
• Carbon Dioxide
• Ethene
• Ethane
