Claim Text:
1. An apparatus for gas spectroscopy of a gas of interest, comprising: a gas cell, said gas cell including a first side, a second side, and an interior, wherein said second side is opposed to said first side and wherein said interior is between said first side and said second side, a first side mirror positioned in said interior adjacent said first side, a second side mirror positioned in said interior adjacent said second side, wherein said second side mirror is opposed to said first side mirror with said interior between said first side mirror and said second side mirror, a gas containment system for introducing the gas of interest into said interior of said gas cell between said first side mirror and said second side mirror, a light source that produces a light beam, a transmitting optical fiber connected to said gas cell that receives said light beam from said light source and directs said light beam into said interior of said gas cell between said first side mirror and said second side mirror and onto the gas of interest in said interior of said gas cell between said first side mirror and said second side mirror, wherein said first side mirror and said second side mirror are positioned relative to each other so that said light beam is reflected between said first side mirror and said second side mirror through the gas of interest in said interior of said gas cell, a receiving optical fiber connected to said gas cell, said optical fiber positioned relative to said first side mirror and said second side mirror so that said optical fiber receives said light beam from the gas of interest in said interior of said gas cell and provides an exit light beam; and a gas spectroscopy analyzer connected to said receiving optical fiber that receives said exit light beam and produces gas spectroscopy data.
