Abstract
The present application relates to a device for extracting volatile components from a sample received in a sample vessel, wherein the sample vessel is closed in a gas-tight manner. The device moreover has a discharge line and a supply line, which protrude into the sample vessel. The supply line comprises a first valve with which a flow of gas through the supply line can be throttled and/or interrupted. A suction opening of a pump is fluidically connected to the discharge line via a first fluid line, such that the pressure conditions in the device can be controlled by the capacity of the pump and by the setting of the first valve. A second fluid line fluidically connects the supply line to an output opening of the pump, such that sample vessel, supply line, discharge line and pump form a closed gas circuit. A trap element with at least one sorption material is fluidically connected to the first fluid line or the second fluid line.
