Abstract:
1. A gas sampling apparatus comprising: sample containers which are two in number further comprising a first sample container and a second sample container into which gas samples are sequentially disposed, a mounting apparatus into which said sample containers are demountably disposed and fluidly connected, said second sample container is identical in construction to said first sample container, said first sample container further comprising a first sample container first end having a first edge wherein said first edge is partially curved inward around the circumference of said first sample container first end, said first edge having first opposing notches, first sample container second end having a second edge wherein said second edge is partially curved inward around the circumference of said first sample container second end said second edge having second opposing notches, a first self-sealing valve demountably and fluidly connected to said first sample container first end, a first self-sealing valve retainer demountably connected to said first self sealing valve and to said first sample container first end whereby said first self sealing valve is fixed and prevented from advancing within said first sample container, a second self-sealing valve demountably and fluidly connected to said first sample container second end, a second self-sealing valve retainer demountably connected to said second self sealing valve and to said first sample container second end whereby said second self sealing valve is fixed and prevented from advancing within said first sample container, said first self sealing valve, when said first self sealing valve retainer is removed, being capable of being advanced within said first sample container while maintaining a seal between said first self sealing valve and said first sample container, whereby said gas samples may be compressed, said second self sealing valve, when said second self sealing valve retainer is removed, being capable of being advanced while maintaining a seal between said second self sealing valve and said first sample container, within said first sample container whereby said gas samples may be compressed, a first annular ring sealably connected to said first self sealing valve, whereby said first annular ring produces a seal against the walls of said first sample container, said first annular ring and said first self sealing valve may be inserted through said first opposing notches and retained within said first sample container first end, a second annular ring sealably connected to said second self sealing valve, whereby said second annular ring produces a seal against the walls of said first sample container, said second annular ring and said second self sealing valve may be inserted through said second opposing notches and retained within said first sample container second end, a plurality of flow directors fluidly attached to said mounting apparatus, said plurality of flow directors sequentially disposing gas into said mounting apparatus and sample containers.
