    Abstract: A method of analysing fluid samples using a bent capillary flow cell, in which method an external UV/visible light ray beam (18) is directed into an elongated section (11) of the flow cell from a bend (14) thereof, this incident light ray beam (18) is limited to a solid acceptance angle (Ω). This solid acceptance angle (Ω) is determined such that light rays (25) which enter the elongated section (11) traverse predominantly the longitudinal axis (16) thereof, i.e. propagate through the fluid sample, providing an improved S/N ratio. Lens means (31, 32) such as ball lenses, may be used at the entrance (14) and exit side (15) of the elongated section (11). A bent capillary flow cell is provided, in which the elongated section (11) deviates by an angle (0) from a line (N) perpendicular to a flat side face (3, 4) of a holding template (1).

    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.

    Abstract: An optical sensor (102) includes a sensor head (112; 304) that has an optical window (312, 314) for directing light into a flow of fluid and/or receiving optical energy from the fluid. The optical sensor (102) also includes a flow chamber (110) that includes a housing defining a cavity (356) for receiving the sensor head (112; 304). In some examples, the flow chamber (110) includes an inlet port (352) defining a flow nozzle that is configured to direct fluid entering the flow chamber (110) against the optical window (312, 314) of the sensor head (112; 304). In operation, the force of the incoming fluid impacting the optical window (312, 314) may prevent fouling materials from accumulating on the optical window (312, 314).

    Abstract: An analytical instrument may have multiple distinct channels. Such may include one or more illumination sources and sensors. Illumination may be delivered to specific locations of a specimen holder, and returned illumination may be delivered to specific locations of a sensor array. Illumination may first pass a specimen, and a mirror or reflector may then return the illumination past the specimen. Optical splitters may be employed to couple pairs of fiber optics proximate a specimen holder. Such channels may further include a plurality of illumination sources positioned on one side of a specimen holder and a plurality of sensors on the other side. The plurality of sensor may capture image of a specimen and a spectrophotometer may concurrently scan the specimen. A plurality of specimens may be imaged and scanned in a single pass of a plurality of passes. Spherical or ball lenses may be placed in an optical path of the illumination to achieve a desired illumination pattern.
