A system for providing optical measurements and detection in optical spectrum analyzers (OSAs) with high dynamic range and high speed is disclosed. The system may include a slit to allow inward passage of an optical beam. The system may also include an optical portion to receive the optical beam. In some examples, the optical portion may include at least one optical splitter to split the optical beam into at least two optical paths. The system may also include an electrical portion to receive the optical beams split into the at least two optical paths. In some examples, the electrical portion may include at least one photodetector to receive each of the split optical beam. The electrical portion may also include at least one amplifier communicatively coupled to each of the at least one photodetector to amplify the split optical beam. The electrical portion may further include at least one analog-to-digital converter (ADC) communicatively coupled to each of the at least one amplifier to convert the split optical beams into digital signals.

A chemical processing system for removing carbon dioxide from a gas mixture using a multicomponent amine-based scrubbing solution includes a spectroscopic evaluation system with a liquid contact probe for spectroscopic investigation, an energy source connected with the liquid contact probe to provide the spectroscopic stimulation energy to the probe, a spectrometer connected with the liquid contact probe to detect the spectroscopic response energy to the probe and to output spectral data corresponding to the spectroscopic response energy, and a machine learning spectral data analyzer connected to the spectrometer for evaluation of the spectral data to determine a concentration value for each of water, amine component and captured carbon dioxide in the scrubbing solution, the machine learning spectral data analyzer being trained for each such component over a corresponding trained concentration range, and optionally over a trained temperature range to provide a temperature-compensated concentration value.

A heating chamber (1) for a heating furnace is proposed, with which electrothermal vaporization of impurities from samples can be effected in order to be able to then analyze them spectrometrically. The heating chamber has a wall (3), a sample reception area (5), a nozzle area (7) and two electrical connection areas (9, 11). The heating chamber (1) is specially configured such that an electric current flows through the wall (3) in such a way that a heating capacity caused by it is higher in the nozzle area (7) than in the sample reception area (5). For example, the electrical connection areas (9, 11) may be arranged in a radial direction remoter from the longitudinal axis (8) than a part of the wall (3) surrounding the nozzle area (7), and the heating chamber (1) may be configured, for example by means of a locally constricted area (13), in such a way that the current between the two electrical connection areas (9, 11) is predominantly conducted radially inwards towards the part of the wall (3) surrounding the nozzle area (7). Advantageous heat distribution in the heating chamber (1) achievable thereby may have a positive effect on the analysis of sample impurities.
