Therefore, the wall thickness of headspace vials is higher compared to standard vials for liquid chromatography: 1.2 mm versus 0.9 mm. Headspace vials are available with flat and rounded bottom. The rounded bottom is more sturdy and therefore more resistant to the high pressure which builds up inside the vial during the heating process.
Fisher Scientific - DWK Headspace vials are characterized by a thicker wall and a rounded bottom, which makes them more resistant to pressure. Shop DWK Life Sciences ;Headspace
standard Schlenk techniques. Synthesis was adapted from Schaak et al.1 1-octadecene (50 mL, 156.6 mmol), oleylamine (30 mL, 91 mmol), nonanoic acid (10 mL, 56.5 mmol) were added to a 500 mL 3-neck flask equipped with a thermowell, condenser, and septum and was degassed at 120 ºC for 1 hour.

An Introduction to Headspace Sampling in Gas Chromatography Phase Ratio Other factors that can affect the concentration of an analyte in the headspace phase are the respective volumes of the sample and the headspace in the sealed vial. The concentration of analyte in the sample and the headspace can be expressed respectively as Equations 2 and 3.

A vial-in-vial method is used, in which the volatile agent is placed in a small inner vial, and the inner vial is capped with a layer of fabric or film to be tested. The agent permeates from the inner vial into an outer headspace vial. The instrument samples the vapor in the outer vial by sampling it and injecting it into the GC for analysis.
