Abstract: Bei einem auf der Wellenlängen-Modulationsspektroskopie (WMS) beruhenden Verfahren zur Gasanalyse wird das erhaltene Messsignal (13) bei einer Oberschwingung der Modulationsfrequenz demoduliert und durch Anfitten einer Sollkurve (19) an den Verlauf des demodulierten Messsignals (13') zu einem Messergebnis (17) ausgewertet.
Um aus Störeinflüssen (z. B: Temperaturänderungen, Änderung der Konzentration von Störgasen) resultierende Änderungen in den Messergebnissen zu reduzieren, werden sowohl das demodulierte Messsignal (13') als auch die Sollkurve (19) mit derselben Filterfunktion (Filter 15, 20) gefiltert, wobei die Filterfunktion zur Unterdrückung von Störsignalanteilen ausgelegt ist, die sowohl mit Nutzsignalanteilen des demodulierten Messsignals (13') als auch mit der Sollkurve (19) interferieren.

Abstract: In an embodiment, an apparatus includes a module assembly and a main assembly. The module assembly includes a module assembly housing, a first face plate and an analysis unit attached to the first face. The main assembly includes a main assembly housing, a second face plate and an engine unit rigidly attached to the second face plate. The engine unit generates a light that passes to the analysis unit via a first lens assembly and a second lens assembly. The first lens assembly is attached to the first face plate and the second lens assembly is attached to the second face plate. The module assembly when attached to the main assembly causes the first and second face plates to act as a single mechanical unit that moves independent of movement of the module assembly housing and/or the main assembly housing.

Abstract: A spectroscopic assembly (7) is provided. The spectroscopic assembly includes a thermal isolation platform, a gas reference cell (40) encasing a gas (41) and attached to the thermal isolation platform, the gas reference cell (40) having at least one optically-transparent window (415), and at least one heater configured to raise a temperature of the encased gas (41). When a beamsplitter (30) is configured to reflect a portion of an input optical beam (20) emitted by a laser (10) to be incident on the at least one optically-transparent window (415) of the gas reference cell (40), the reflected portion of the input optical beam (20) is twice transmitted through the gas (41). When a detector (350) is configured to receive the optical beam (25) twice transmitted through the gas (41), a feedback signal (50) is provided to the laser (10) to stabilize the laser.

Abstract: A Raman head is provided capable of operating at high surrounding pressures. The Raman head has housing having a first, sealed chamber filled with an incompressible liquid and a second chamber that is open to the surrounding environment. At least one bellows can be used to equalize pressure between the first sealed chamber and the surrounding environment. A planar side of a pair of plano-concave lens is positioned within the first chamber and the concave side of each plano¬ concave lens is positioned within the second chamber of the Raman head. Light emitted as a result of a laser beam in communication with the pair of plano-concave lens can be analyzed by a Raman analyzer.

Abstract: Devices, methods and systems for making optical measurements of a fluid at elevated pressures and temperatures are disclosed. A cell is designed for the optical spectroscopic measurements of fluids or gas using light from ultra violet (UV) to far infrared wavelengths, among other wavelengths. A cell is described that is well suited for applications using very small fluid volumes, on the order of micro liters, such as microfluidic systems. Some described embodiments are suited for very high pressure and temperature environments (for example, 20 kpsi or greater at 175 degree C. or greater). Such conditions, for example, may be found in oilfield downhole environments. Some embodiments provide are inexpensive, and make use of replaceable lenses that are used as a pressure barrier and for collimation of the optical beam path for spectroscopic measurements.
