Hydrocarbon Analyzers Manufacturers

A hydrocarbon analyzer is used for rapidly measuring both methane and nonmethane hydrocarbons. The analyzer includes a nonmethane hydrocarbon absorbing first column connected in series with a methane absorbing second column. A sample gas is propelled in a carrier gas through a carrier gas line into the first and second columns via a change-over valve for switching between a branched line connected between the carrier gas line. The first flame ionization detector is used for measuring nonmethane hydrocarbons and a second flame ionization detector is connected to the second column for measuring methane. The change-over valve switches from a gas sample introducing position to a backflush position, so that the sample gas is introduced into the first nonmethane hydrocarbon absorbing column where the nonmethane hydrocarbons are absorbed.
