Oct 01, 2013 · In Figure 2, a headspace oxygen increase plotted in the top-right graph from plastic-vial samples stored for a week in the −80 °C freezer is due to permeation effects rather than a leak. We attribute the oxygen increase to samples being stored under normal atmospheric conditions for four days before being placed in cold storage.

glass surface of glass, deactivated vials may be a good choice. The glass vials are treated with gas phase reactive organosilane to produce a hydrophobic glass surface. Deactivated vials can be stored dry indefinitely. Polypropylene Plastic Polypropylene (PP) is a non-reactive plastic and can be used where glass is not an appropriate option.
20 mm Aluminum Seals. Seals for Headspace Vials are available in aluminum, magnetic and pressure release. Pressure release seals offer a safety feature where the scored aluminum seal will open if the internal pressure reaches 3.0 ± 0.5 bar (1 bar equals approximately 14.5 psi).

vials, the HS uses a single-vial oven to equilibrate the sample at the desired temperature. If configured with the 111 sample vial tray, the HS uses a 12 vial oven for equilibrating samples at temperature. Since the longest hold time in headspace analysis is typically the equilibration time, using a multi-vial oven allows the higher capacity HS to
