Headspace Technique - an overview | ScienceDirect Topics

This approach uses a small volume of liquid sample (5–50 μl) placed into a standard headspace vial and heated to completely vaporize the sample. 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 this technique appropriate only where very low detection limits
