Abstract

A device for preparing a liquid sample for a direct injection of a corresponding gaseous sample to a micro-gas chromatograph includes: a fluid space and a gas space, which spaces are separated by a semipermeable separating layer, the fluid space including a supply line for the liquid sample, and the gas space having an outlet connectable with the gas chromatograph. The fluid space and/or the gas space is associated with at least one heating element. The device absorbs a sample volume of approximately 10 μl to 30 μl. The separating layer has a thickness of 10 μl to 300 μl and pores having a size between 0.05 μl and 5 μl.
