Abstract: Systems and methods of the present disclosure are directed to detecting species within a fluid using a multi-pass absorption cell and a spectrometer. The absorption cell includes a plurality of mirrors arranged in a manner such that a detection light traverses multiple passes through the fluid within the absorption cell. In some implementations, the detection light is reflected by the plurality of mirrors to form optical paths in more than one plane. The system also includes an electronic unit configured to receive and process spectral data from the spectrometer. In some implementations, the electronic unit communicates with at least one computational unit over a communication interface to send a portion of the spectral data for processing. The electronic unit may also receive processed data from the computational unit.

Abstract: A diffusion chamber for determining different parameters of an aqueous substance includes a vertical central cylinder having a sample chamber for receiving a substance sample and a needle-shaped pH-measuring sensor having a measuring tip which is brought into contact with the substance sample. A spectrophotometer having glass-fiber optics is configured to penetrate the substance sample. A gas supply into the sample chamber is configured to provide a variable gas exposure of the substance sample when determining parameters. A needle of the pH-measuring sensor is inserted into an obliquely extending groove of a slid-in sample slide. A sealing ring on the sample slide is pressed against the central cylinder by means of an inserted spacer ring, the sample chamber is tightly sealed with respect to gases from the surroundings of the diffusion chamber, and a minimum distance is maintained between the lower collimating lens and the substance sample.

Abstract: Spectrally analyzing an unknown sample (10A) includes (i) providing a spatially homogeneous region (10B) of the unknown sample (10A); (ii) directing a plurality of interrogation beams (16) at the spatially homogeneous region (10B) with a laser source (14), (iii) acquiring a separate output image (245) while the unknown sample (10A) is illuminated by each of the interrogation beams (16) with an image sensor (26A); and (iv) analyzing less than fifty output images (245) to analyze whether a characteristic is present in the unknown sample (10A) with a control system (28) that includes a processor. Each of the interrogation beams (16) is nominally monochromatic and has a different interrogation wavelength that is in the mid-infrared spectral range.
