Abstract

The present invention relates to a method of enriching a volatile substance or volatile substances from a gas flow that has already been generated and metering the volatile substance(s) to an analytical instrument in a limited gas flow, characterized by either sucking or pressing the gas flow via a first switching valve to an adsorber in which the volatile substance or volatile substances is/are adsorbed, and causing the gas flow freed from said substance or substances to leave the system via at least said first switching valve; causing a controlled amount of inert gas to flow via the first switching valve to the adsorber, which is heated with the aid of an infusion pump and through said adsorber while taking up the volatile substance or volatile substances, again via the first switching valve and via a second switching valve to the infusion pump; and delivering the inert gas together with its volatile substance or volatile substances content to the analytical instrument via said infusion pump and said second switching valve. The present invention also relates to apparatus for carrying out the method.
