Abstract: A method and apparatus is provided for concentration determination of at least one component in an acid catalyst for hydrocarbon conversion containing an unknown concentration of an acid, an acid-soluble-oil (ASO), and water. An instrument configured for measuring a property of the acid catalyst, has responsivities to concentrations of one of the acid, ASO, and water, substantially independent of the concentrations of the others of the acid catalyst, ASO, and water. A temperature detector is configured to generate temperature data for the acid catalyst. A processor is configured to capture data generated by the temperature detector and the instrument, and to use the data in combination with a model to determine a temperature compensated concentration of the one of the acid, the ASO, and the water. Optionally, one or more other instruments configured for measuring other properties of the liquid mixture may also be used.

Abstract: A target gas sensor employing a radiation source (20) and a radiation sensor (30) including a reference radiation detector (31), a target radiation detector (32), a temperature sensor (34), a temperature controller (35) and a target gas detection processor (37). In operation, radiation source (20) controls a propagation of radiation (RAD) through a gas mixture (GM) contained by an airway (10) to radiation sensor (30). Reference radiation detector (31) generates a reference detection signal (RD) indicative of a detected magnitude of a reference wavelength (λREF) of the radiation, and target radiation detector (32) generates a target detection signal (TD) indicative of a detected magnitude of a target wavelength (λTG) of the radiation. Temperature sensor (34) senses a temperature of radiation detectors (31, 32) whereby temperature controller (35) regulates a heating of the radiation detectors (31, 32) relative to a regulated detector temperature (TREG). Target gas detection processor (37) measures the target gas concentration within the sample of the gas mixture (GM) as a function of an absorbing spectral response ratio (SRRA) and a temperature compensation (TPC).

Abstract: Validation verification data quantifying an intensity of light reaching a detector of a spectrometer from a light source of the spectrometer after the light passes through a validation gas across a known path length can be collected or received. The validation gas can include an amount of an analyte compound and an undisturbed background composition that is representative of a sample gas background composition of a sample gas to be analyzed using a spectrometer. The sample gas background composition can include one or more background components. The validation verification data can be compared with stored calibration data for the spectrometer to calculate a concentration adjustment factor, and sample measurement data collected with the spectrometer can be modified using this adjustment factor to compensate for collisional broadening of a spectral peak of the analyte compound by the background components. Related methods, articles of manufacture, systems, and the like are described.
