Abstract
A gas sampling apparatus and process is provided in which a standard crimping tool is modified by an attached collar. The collar permits operation of the crimping tool while also facilitating the introduction of a supply of gas to be introduced into a storage vial. The introduced gas supply is used to purge ambient air from a collection chamber and an interior of the sample vial. Upon completion of the purging operation, the vial is sealed using the crimping tool.
Claims12
An apparatus for introducing a gas sample into a container comprising:
- a crimping tool comprising a handle, a plurality of jaw members, and an actuator mechanism;
- a collar operatively engaging said crimping tool so as to enclose said plurality of jaw members when said actuator mechanism of said handle is engaged;
- a chamber defined by an interior of said collar, said chamber having an opening at one end and opposite said crimping tool;
- an inlet having a first end and a second end, said inlet defined within a sidewall of said collar and being in communication at said first end with said chamber and said second end providing communication with an exterior of said collar;
- wherein a sample of a gas is introduced through said inlet into an interior of said chamber, said chamber further adapted for placement of a vial within said chamber for receiving a portion of said gas within said vial.
A process for collecting a gas sample within a vial comprising:
- providing a crimping tool comprising, a plurality of jaw members, and an actuator mechanism, said crimping tool further comprising a collar operatively engaging said crimping tool so as to close said plurality of jaw members when said actuator mechanism is engaged;
- positioning a collection vial within a chamber defined by an interior of said collar;
- introducing a sample gas supply to said chamber, said sample gas supply purging both said chamber and an interior of said sample vial of ambient air;
- and,
- sealing said sample vial using said crimping tool once a representative gas sample has been established in an interior of said vial.
An apparatus for introducing a gas sample into a container comprising:
- a crimping tool comprising a plurality of jaw members, said jaw members closing in response to an actuator mechanism;
- a collar operatively engaging said crimping tool, said collar defining a bore extending therethrough, said bore having a first opening adapted for receiving a portion of said crimping tool within a first end of said collar, said bore having a second opening in communication with an exterior of said collar;
- an inlet having a first end and a second end, said inlet defined within a sidewall of said collar and being in communication at said first end with said bore and said second end providing communication with an exterior of said collar;
- wherein a sample of gas is introduced through said inlet into said bore, said second bore opening further adapted for placement of a vial within said chamber for receiving a portion of said gas within said vial.
