Abstract: Aspects relate to a compact and low-cost gas analyzer that can be used for different types of gas analysis, such as air quality analysis. The gas analyzer can include a light source, a gas cell configured to receive a sample (e.g., a gas under test), a spectral sensor including a spectrometer and a detector, and an artificial intelligence (AI) engine. Light can enter the gas cell and interact with the sample to produce output light that may be measured by the spectral sensor. The resulting spectrum produced by the spectral sensor may be analyzed by the AI engine to produce a result. The gas analyzer further includes a self-calibration component configured to enable calibration of the sample spectrum to compensate for spectral drift of the spectral sensor.

Abstract: Für eine sensitive und flexible Messung eines gasförmigen oder festen Stoffes in einer Äbgaswolke ist vorgesehen, dass ein Lichtstrahl (4) zwischen zwei Spiegelungseinheiten (3, 5) mehrfach reflektiert wird oder der Lichtstrahl (4) an einem Umlenkspiegel (11) zu einem Rückstrahl (14) reflektiert wird und der Rückstrahl (14) eine Anzahl weiterer Reflexionen zwischen den Spiegelungseinheiten (3, 5) durchführt und dabei das Messvolumen (7) mehrfach durchdringt, wobei die Mehrzahl n an Reflexionen des Lichtstrahls (4) durch Variieren des ersten Winkels (a) verstellt wird, um die Mehrzahl n an Reflexionen zwischen erster Spiegelungseinheit (3) und zweiter Spiegelungseinheit (5) einzustellen. Der Rückstrahl (14) wird nach den Reflexionen von dem zumindest einen Detektor (21) erfasst und eine den zumindest einen gasförmigen oder festen Stoff charakterisierende Lichteigenschaft des Rückstrahls (14) gemessen.

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.
