    Abstract: The present disclosure generally relates to a standalone gas extraction and detection system comprising a gas extraction chamber operable to receive a wellbore fluid and a carrier gas; a gas detection chamber in fluid communication with the gas extraction chamber, the gas detection chamber comprising reflective surfaces operable to receive infrared radiation (IR) and an extracted gas sample from the gas extraction chamber; an open-path detector operable to detect the IR in the gas detection chamber; and a shaft extending through the gas extraction chamber and the gas detection chamber of the standalone gas extraction and detection system.

    Abstract: Aspects relate to an optical fluid analyzer including a fluid cell configured to receive a sample fluid. The optical fluid analyzer further includes optical elements configured to seal the fluid cell on opposing sides thereof and to allow input light from a light source to be sent through the fluid cell and output light from the fluid cell to be input to a spectrometer. The optical fluid analyzer further includes a machine learning (ML) engine, such as an artificial intelligence (AI) engine, that is configured to generate a result defining at least one parameter of the fluid based on a spectrum produced by the spectrometer.

    Abstract: A gas and vapor analyzer system and method of detecting a gas or vapor sample are provided. An FTIR spectroscopy system of an analyzer system comprises an interferometer adapted to modulate an excitation signal. A gas cell is adapted to receive the modulated excitation signal and focus the modulated excitation signal within the gas cell via an input lens. An off-axis multiple reflection geometry is adapted to receive the focused modulated excitation signal and pass the focused modulated excitation signal through a gas or vapor phase specimen via a plurality of beam paths skewed relative to a longitudinal axis of the cell to generate an optical sample signal. An exit lens is adapted to direct the optical sample signal from the gas cell to an IR radiation detector, and a controller is adapted to identify a detected gas and vapor sample based on the optical sample signal.
