Multiple headspace extraction (MHE) is an absolute quantitative method used in static headspace—GC. In principle it is dynamic gas extraction, carried out stepwise and establishing equilibrium conditions in each step. The concentration of the analyte in the headspace decreases exponentially during the series of extraction steps: by proper mathematical extrapolation the total peak area

Weigh out 2.0 g of the brain matrix control into 20 mL headspace vials and aliquot the entire batch. Label the vials. The brain matrix control is stored frozen until removed for analysis. The brain matrix control is validated using at least 6 aliquots (see tissue procedure) on a headspace instrument.
Headspace vials with different volumes and outside diameters are available in a variety of bottom shapes.Designed to use separating organic and inorganic compounds for analysis, chromatography vials come in different finishes to guarantee chemical compatibility. Autosampler compatible closures come in different colors, sizes, and septa materials. Offered with a write-on patch, possible
Headspace ND20 (ND18) Headspace Vials might differ in: Volume (5ml, 10ml, 20ml) Rounded or flat bottom A rounded bottom is more sturdy and thus more resistant to the high pressure within the vial during the heating process. Furthermore the vial slides more easily into the heating block when being transported by a magnet.
