Introduction

Natural gas is a fossil fuel. Millions of years ago, the remains of plants, animals, and
micro-organisms were buried underneath layers of soil and sediment. Due to the weight of the soil
and sediment, the pressure and temperature increased. This resulted in the slow transformation
of the organisms into natural gas and oil.
The composition of natural gas varies widely. Natural gas is a combustible mixture of
hydrocarbon gases that mainly consists of methane, smaller amounts of light hydrocarbons such
as ethane, propane, n-butane, n-pentane, hexanes plus, and other gases such as nitrogen, carbon
dioxide, oxygen, hydrogen, and hydrogen sulfide. Natural gas can also contain traces of argon,
helium, neon, and xenon. Natural gas in its pure form is colorless and odorless.
Natural Gas Analyzers have been designed to analyze the different compositions of natural gas.
