    Abstract: A method is disclosed which comprises maintaining a scrubber medium at a temperature in a range of -20°C to 85°C, the scrubber medium comprising nanoparticles of a reactive metal oxide material having first aerodynamic diameters of less than 250 nm that are adhered to carrier particles having second aerodynamic diameters in a range of 10 to 250 microns and that are inert relative to one or more background compounds, wherein a mass ratio of the reactive metal oxide to the carrier particles is in a range of 20% to 30%, and wherein the nanoparticles of the reactive metal oxide are adhered to the carrier particles by one or more of van der Waals and electrostatic forces. In a further step a gas mixture is contacted with the scrubber medium while the scrubber medium is maintained at the temperature, the gas mixture comprising a reactive compound and the one or more background compounds, the reactive compound comprising a gas-phase acid, the contacting causing the reactive compound to react with the reactive metal oxide material to convert the reactive compound and at least one metal oxide site on the nanoparticles to one or more metal-anion surface compounds. An apparatus, a composition and a refreshing method are also disclosed.

    Abstract: A differential absorption spectrum for a reactive gas in a gas mixture can be generated for sample absorption data by subtracting background absorption data set from the sample absorption data. The background absorption data can be characteristic of absorption characteristics of the background composition in a laser light scan range that includes a target wavelength. The differential absorption spectrum can be converted to a measured concentration of the reactive gas using calibration data. A determination can be made whether the background composition has substantially changed relative to the background absorption data, and new background absorption data can be used if the background composition has substantially changed. Related systems, apparatus, methods, and/or articles are also described..

    Abstract: The present disclosure relates to a computer-implemented method for forecasting calibration spectra including a step of providing a machine learning model trained using historical calibration data corresponding to different gas species at different pressures. The computer-implemented method also includes steps of performing a calibration scan of one gas species at one pressure using an analyzer and generating calibration curves for the analyzer corresponding to one or multiple gas species at multiple pressures using the machine learning model and the calibration scan. Thereafter, a spectrum is obtained using the analyzer, and a concentration measurement is generated using the spectrum and at least one of the calibration curves.

    Abstract: A light source module may include a base with a support feature protruding from a surface of the base and securing a light source to direct radiation away from the surface. A lens cells may be attached proximate to the surface, optionally by being secured within a sleeve that is attached at one end to the surface. A multi-conductor part may include electrical conductors and a base temperature sensor that contacts the base. The base temperature sensor may be electrically connected to at least one of the plurality of conductive elements and further connected to an optical ignition safety protection system configured to interrupt current to the light source if the base temperature sensor indicates that a temperature of the light source is outside of a safe range.
