Gas sampling valve apparatus and method

A system for obtaining a fluid sample, comprising:

• a fluid container comprising a valve assembly, the valve assembly comprising a core valve, wherein a pin of the core valve is biased to a first, closed position;
• and
• a fluid sampling apparatus comprising a chuck system, the chuck system comprising a transfer tube, said transfer tube comprising a central bore with a raised internal profile;
• wherein the raised internal profile of the transfer tube is configured to displace the pin of the core valve to a second, open position upon the valve assembly being seated into the chuck system, thereby isolating a fluid communication path between the first core valve and the chuck system.

A method of collecting a fluid sample, comprising:

• providing a fluid container comprising a valve assembly, the valve assembly comprising a core valve, wherein a pin of the core valve is biased to a first closed position;
• providing a fluid sampling apparatus comprising a chuck system, the chuck system comprising a transfer tube, said transfer tube comprising a central bore with a raised internal profile,
• wherein the raised internal profile of the transfer tube is configured to displace the pin of the core valve of the valve assembly to a second, open position upon the valve assembly being seated into the chuck system, thereby isolating a fluid communication path between an interior volume of the fluid container and the chuck system through the core valve;
• and
• seating the valve assembly of the fluid container into the chuck system of the fluid sampling apparatus in a manner which displaces the pin of the core valve, thereby forming the fluid communication path.
