20 mL headspace crimp top vials or screw top vials directly; no effort was made to purge the vials with an inert gas prior to capping. These vial blank samples were used for blank background and potential septa contamination evaluation. Solvent blank samples were prepared by adding 1 mL of solvent blank into a vial and then capping the vial

I have observed reproducibility problems while analysing alcohols (methanol, iso-propanol, butanol) by headspace, using DMSO as diluent. On 2 occasions, using 2 different methods (and 2 different solvent mixes that contain alcohols) the reproducibility has been a lot worse for the alcohols than for the other components.
