Importance of vial volume in headspace analysis

Oct 13, 2005 · The mass in the headspace depends on the partition co-efficient (as for the alcohols) but also on the volume of the headspace (a bigger volume allows more analyte to partition out of the water) and on the mass of analyte in the original water sample. A large headspace implies a small sample containing a low mass of BTEX, which is lowered still
