Abstract: A sensing system (16) for monitoring a composition of a downhole fluid (15) in a well (16), where the sensing system (16) includes: a light source (41), a waveguide (21), an evanescent field sensing element (22) that is indirect contact with a downhole fluid (15), and a detector (25, 43, 53, 63). The light source (41) is operable for emitting a beam and includes a frequency comb generator (42) configured to modify at least a portion of the beam into a sensing comb beam. The evanescent field sensing element (22) provides attenuated internal reflection of the sensing comb beam at the interface between the evanescent field sensing element (22) and the downhole fluid (15), and the portion of the sensing comb beam interacts with the downhole fluid (15) to form at least a portion of an interacted beam. The detector (25, 43, 53, 63) obtains a spectral distribution of the interacted beam.

Abstract: A method of detection of a status of cells within a cell culture is described. The method is based on comparing an IR spectrum of a test sample obtained from the cell culture with an IR spectrum of a control sample or samples or with an IR spectrum of a sample or samples obtained at an earlier time point in the cell culture and correlating differences between the spectra with the status of the cells. The status may be classified into healthy or unhealthy. The test sample may or may not contain cells. The test sample may contain cell fragments, cell components or cell media, or may be cell supernatant. The comparison may be performed using a predictive model based on pattern recognition algorithms, such as support vector machines SVM, linear discriminant analysis LDA, principal component discriminant function analysis PC-DFA, neural networks, or random forests). The analysis results may be used to monitor and/or control the cell culturing process.

Abstract: Aspects relate to a spectroscopic analyzer device that can be used for biological sample detection, and specifically for virus infection detection. The spectroscopic analyzer device includes a spectrometer, such as a micro-electro-mechanical systems (MEMS) based infrared spectrometer, and an artificial intelligence (AI) for screening of viral samples. In addition, the spectroscopic analyzer device includes a light source and a disposable optical component configured to receive a sample and to facilitate light interaction with the sample.

Abstract: Portable optical device (100) providing a large spot size spectrometer. The optical device includes an optical head (102), an optical window (106), and a spectrometer (104). The optical head (102) includes a plastic moulded part (105) having an aperture (115) and a plurality of reflectors (112) around the aperture (115) formed therein. Each reflector (130) may include a respective lamp (110) assembled therein. The optical window (106) is configured to receive a sample (108), to pass input light (128) from the lamps (130) to the sample (108) and to pass scattered light from the sample (108) towards the aperture (115). The aperture (115) is configured to filter a first portion of scattered light containing unusable sample information and to pass a second portion of the scattered light to the spectrometer (104).
