Natural gas is a combustible mixture of hydrocarbon gases. While natural gas is formed primarily of methane, it often includes ethane, propane, butane, pentane and even higher molecular weight hydrocarbons. It is important to be able to quantify the composition of various compounds present in the natural gas to determine the mixture of hydrocarbons in the gas in a rapid and cost-effective manner.

The ability to perform hundreds of chromatographic analyses per day also provides a cost-effective solution to sample screening and process development in the laboratory. Whereas such projects can take months using a conventional long-column GC, with zNose® it is often possible to complete development projects in less than a week. It is not difficult to see how zNose® pays for itself in less than 30 days.
