    摘要: A sensor is described for optically determining the concentration of an analyte in a body fluid. This sensor comprises a needle arrangement which has at least one hollow needle having a hollow space extending from the distal end to the proximal end, the distal end of which is suitable for lancing. The proximal end of the needle opens into a chamber in which liquid that enters through the distal end of the needle can be collected. A window which is at least partially permeable to infrared radiation is in direct contact with the chamber.

    摘要: Various embodiments of the application provide a photoacoustic sensor, which includes: a gas cell having an opening; a light source to generate a radiation to radiate sample gas within the gas cell; a detector to detect the sample gas within the gas cell, and to generate electrical signals in response to acoustic signals generated by pressure fluctuations of the radiated sample gas caused by the radiation; and an active valve having a speaker aligned with the opening of the gas cell. The speaker having a voice coil and a diaphragm attached to the voice coil. A control signal is applicable for the speaker to control access of the gas cell. During sampling, the control signal causes the voice coil of the speaker to repeatedly or constantly lift the diaphragm from contact with the opening of the gas cell to allow sample gas enter the gas cell. While during detecting, the spring force of the voice coil causes the diaphragm in tight contact with the opening of gas cell to seal the gas cell.

    摘要: The application relates to a method and a microelectronic sensor device for making optical examinations in an investigation region (13) at the contact surface (12) of a carrier (10), wherein an input light beam (L1, L1′) is sent from a light source (20) towards the investigation region (13), and wherein an output light beam (L2, L2′) coming from the investigation region (13) is detected by a light detector (30). An evaluation unit (50) that is coupled to the light detector (30) is adapted to determine the wetting grade of the investigation region (13) based on a characteristic parameter of the output light beam (L2, L2′), e.g. its intensity. In a preferred embodiment, the evaluation unit (50) is adapted to determine a change in the light intensity caused by a liquid contacting the contact surface (12). The wetting grade may particularly be detected in a test region (14) that is located adjacent to the investigation region (13) and that has a higher roughness than the investigation region (13).

    摘要: With a measuring instrument for measuring sample particles moving in a cuvette, for example for measuring a zeta potential or the Brownian size the particles, with a filling device for filling and an emptying device for emptying the cuvette mounted on the ends thereof and with devices for irradiating and for monitoring the particles, it is problematical always to position the cuvette correctly or in a defined manner relative to the direction of radiation and to the monitoring device. To resolve this problem, it is proposed that the cuvette member is mounted by means of a cuvette bearing and the filling and the emptying device are fastened exclusively to the cuvette in such a way that the position of the cuvette relative to the surroundings thereof is determined and defined exclusively by the cuvette bearing.

    摘要: A downhole fluid sample container includes a fluid sample container detachably coupled to a downhole sub, the fluid sample container having an internal chamber for receiving the downhole fluid. At least one semimetal (for example, silicon or germanium) window is coupled to the fluid sample container, the window being substantially transparent to electromagnetic energy wavelengths within a selected band. A method includes transmitting electromagnetic energy from an electromagnetic energy source to downhole fluid through at least one semimetal window in a container, receiving an electromagnetic energy response with a spectrometer, and estimating the downhole fluid property based at least in part on the electromagnetic energy response.
