The present invention relates to a method of operating a flame ionization detector comprising providing a hydrogen containing fuel gas, providing an oxygen containing oxidizing gas, burning the fuel gas with the oxidizing gas to produce a flame, providing a sample gas to the flame to produce an at least partially ionized sample gas, wherein the sample gas contains at least one organic compound and a carrier gas, and measuring a current induced by the at least partially ionized sample gas in an electrode of the flame ionization detector. It is provided that the oxidizing gas comprises oxygen in an amount of 50 to 90 vol % of the oxidizing gas and helium in an amount of at least 10 vol % of the oxidizing gas. An arrangement comprising a flame ionization detector and a gas mixture for use in a flame ionization detector are also part of the invention.
A method of operating a flame ionization detector comprising:
A measuring arrangement adapted to measure a hydrocarbon content of a gas mixture including a flame ionization detector, the arrangement comprising:
A gas mixture for use in a flame ionization detector adapted to be used as an oxidizing gas in the flame ionization detector, characterized in that the gas mixture comprises oxygen in an amount corresponding to between 50 and 90 vol % of the oxidizing gas and helium in an amount corresponding to at least 10 vol % of the oxidizing gas.
