Headspace Technique - an overview | ScienceDirect Topics

Headspace Technique. Headspace techniques are based on Henry’s law, which states that the ratio of a dissolved substance in aqueous solution to the substance in the vapor in a sealed glass vial is constant, depending on temperature. From: Encyclopedia of Analytical Science (Third Edition), 2019.

Novel techniques for enhancing sensitivity in static

Apr 16, 2010 · Instrumental methods include use of a PTV inlet as interface between headspace sampling and the column, use of sorbent traps between the sampling vial and the GC and use of the GC as a direct interface between headspace and MS. Fundamentally, these do not alter the extraction process but they enhance sensitivity by increasing the instrument
