Abstract
In order to provide information on the suitability of commonly used gas storage vials for air transport, we tested two vial types on their ability to preserve defined nitrous oxide concentrations and excess pressure when exposed to low pressure, low temperature and puncture by needles. Unlike in Crimp Cap vials, in Exetainers® no nitrous oxide loss following low pressure storage was detectable. Tightness of Exetainers® following multiple puncture was best using a small needle diameter. Pressure loss following 5, 10, or 25 punctures was lowest in the Exetainers®. We conclude that Exetainers® are suitable for storing gas samples for an extended period of time during aircraft transport.
