It is applicable to the measurement of H 2 S in natural gas, liquefied petroleum gas (LPG), substitute natural gas, landfill gas, sewage treatment off gasses, recycle gas, flare gasses, and mixtures of fuel gases.

This method can also be used to measure the hydrogen sulfide concentration in carbon ://   DIMETHYL SULFIDE PHENOL P-XYLENE TOLUENE BENZENE AMMONIA Hydrogen Sulfide ÊCrude Oil ÊAsphalt ÊResidual Fuel & Components ÊMid-Distillates & Blend Components ÊGasoline & Blend Components ÊNatural Gas, Propane, LPG Petroleum Streams Where H2S Found.

Other beneficial properties of natural gas are a high ignition temperature and a narrow flammability range, meaning natural gas will ignite at temperatures above °degrees and burn at a mix of 4 – 15% volume in air (St. Lawrence Gas, ).
