Gas chromatography (GC) is a chromatography technique where the separation of individual components (analytes) from a sample relies on their differing distribution between a mobile and stationary phase. The mobile phase carries the analytes through the stationary phase. In GC‚ it’s an inert gas (usually helium or nitrogen). The gas must be inert‚ so it won’t react with the sample to give a false reading. The stationary phase is a substance fixed in place to which the sample adsorbs because

Biogas as used in two different systems: an instant‚ gas water-heater used to generate hot water for farm use‚ and a modified piston engine driving an electrical generator of one phase‚ I kW output‚ fuelled directed by the gas. Operation of both systems was satisfactory. The unit is being used to demonstrate the technology for potential users (mostly farm owners). Key
