This approach has the benefit of avoiding the liquid–headspace equilibrium that must be considered in other headspace techniques ; however, the small volume of sample used makes
Therefore, the wall thickness of headspace vials is higher compared to standard vials for liquid chromatography: 1.2 mm versus 0.9 mm. Headspace vials are available with flat and rounded bottom.

With this method it is possible to analyze nine samples per hour with a relative standard deviation of 3.9% at a 19‐μl. air level (i.e., 5 mcg. of oxygen), which corresponds to approximately 2% of the theoretical gaseous void volume of a typical 1‐ml. ampul product.
The general procedure, described in ASTM standard E1388, for direct headspace analysis requires the sample in its packaging container to be placed in an oven heated to 60–90 C for about 30 min. A sample of the headspace is then extracted using a gas syringe (previously flushed with air and heated).
