摘要： A method for determining a concentration related information (190) of a solution, the solution comprising one or more kinds of solutes, comprises obtaining measurement information (110) about an interaction of an electromagnetic radiation (464) with the solution. The wavelength of the electromagnetic radiation (464) is adapted to an absorption wavelength of the solvent of the solution. Further, the wavelength of the electromagnetic radiation (464) is within a range, in which the absorption of the solution decreases with increasing concentration. The method further comprises mapping the measurement information to the concentration related information (190) using a mapping correlation, wherein the mapping correlation is independent of the one or more kinds of solutes in the solution.

摘要： Beschrieben werden ein IR-spektrornetrisches Verfahren, ein zugehöriges Reflexionselement und ein Bauteil. Das IR-spektrometrische Verfahren umfasst mindestens die Schritte: a) Bereitstellen einer IR-Lichtquelle und eines Mittels zur spektralen Analyse sowie eines Reflexionselements (2) welches mindestens eine erste Oberfläche (6), die eben ist, und eine zweite Oberfläche (3), die strukturiert und parallel zur ersten Oberfläche ist, aufweist und wobei die Strukturierung eine diverse Reflexion eines einfallenden IR-Lichtstrahls (4) bewirkt und wobei das Reflexionselement (2) aus einem Material gefertigt ist, welches mindestens teilweise durchlässig für IR-Licht (4, 5) ist, b) Anordnen des Reflexionselements (2) zum Verbleib in einer zu vermessenden viskosen Probe (1) zum Zeitpunkt t0, wobei die erste Oberfläche (6) des Reflexionselements (2) exponiert ist, c) Bestrahlen des Reflexionselements (2) auf der ersten Oberfläche (6) mit einem IR-Lichtstrahl (4) zu einem beliebigen Zeitpunkt tx ab dem Zeitpunkt t0 unter einem Einfallswinkel (γ) der kleiner als der Winkel der Totalreflexion ist, d) Aufnehmen des Spektrums, des an einer Grenzfläche zwischen der zweiten Oberfläche (3) des Reflexionselements (2) und der Probe (1) reflektierten IR-Lichts (5) mit dem Mittel zur spektralen Analyse. Die Strukturierung der zweiten Oberfläche (3) des Reflexionselements (2) bewirkt eine diverse Reflexion eines einfallenden IR-Lichtstrahls durch eine Vielzahl an Streuzentren. Zusätzlich ist ein Bauteil, in dem ein solches Reflexionselement zur Durchführung des Verfahrens eingebracht ist, angegeben. Das Verfahren verbessert die Vergleichbarkeit von Spektren, da Einflüsse des Messaufbaus und des Probenortes minimiert sind.

摘要： A composition sensor (250) for measuring the composition of fluid mixtures (such as, for example, oil, water, and gas composition of an oil well) is presented. A system for gathering information about physical properties in a lateral section of a well, such as an oil well, is presented. The system comprises a mobile vessel (200) with the composition sensor (250) attached. The composition sensor (250) includes a plurality of high-brightness emission sources having respective spectrally narrow wavelength emission bands in the near-infrared region, e.g. in the region between 1400-1800 nm. The wavelength emission bands may overlap absorption wavelength bands of the composition. The wavelength emission bands are time multiplexed, and may be wavelength multiplexed, prior to emission through the fluid mixture. The composition sensor (250) includes a pair of opposing arms separated by a distance that defines a length of a measurement flow channel of the composition sensor. The arms may rotate to measure composition at different angular position of a pipe in a lateral section of an oil well.

摘要： A device for monitoring a bioreactor is configured for in-situ analysis, e.g., by NIR, without the need for withdrawing a sample into a sample cell or into an ex-situ arrangement. The device can be inserted into a port of the bioreactor and provides a sample detection region defined by an optical element such as a lens and a photodetector. The electrical signal obtained from a photodetector that is part of the device can be directed to an analyzer via a detachable electrical connection.
