    摘要: Systems and methods for determining the osmolarity of a sample are provided. Aspects of the subject methods include contacting a sensing surface of a sensor with a sample, and generating one or more data sets over a time interval, wherein the data sets are surface plasmon resonance data used to determine the osmolarity of the sample. The subject methods find use in determining the osmolarity of a sample, such as a biological sample (e.g., a tear fluid), and in the diagnosis and/or monitoring of various diseases and disorders, such as, e.g., dry eye disease.

    摘要: Described is a drop detection apparatus (11, 11a) for detecting drops (TR) that exit a metering valve (DV) and move along a path. The drop detection apparatus (11, 11a) comprises an optical waveguide arrangement (L) having a first optical waveguide (L1) and a second optical waveguide (L2). The first optical waveguide (L1) and the second optical waveguide (L2) are arranged across from each other, in a space through which the path of the drop (TR) extends, in such a way that a light beam (LS) emitted by the first optical waveguide (L1) intersects the path (T) of the drop (TR) and is then coupled into the second optical waveguide (L2). The drop detection apparatus (11, 11a) additionally comprises a light signal generation device (70) for coupling a light beam (LS) pulsed at a carrier frequency into the first optical waveguide (L1). The drop detection apparatus (11, 11a) further comprises a light evaluation device (80) for evaluating the light beam (LS) coupled into the second optical waveguide (L2) in order to determine whether a drop (TR) has been dispensed by the metering valve (DV). A method (500) for detecting a drop (TR) is also described.

    摘要: Embodiments of the invention comprise apparatus and methods for detecting the presence of a substance in a test material using a plurality of wavelength-specific couplers (e.g. tilted fibre gratings) which provide a spatially distributed multi-node all-optical measurement system. Each node of the measurement system can comprise an optical module that is sensitive to the intensity of a limited band of wavelengths. The node is thus capable of detecting the presence of an absorption peak in a spectrum without having to obtain the full spectrum. By providing a plurality of optical modules that are sensitive to different wavelengths, the spectral signature of different substances may be monitored without having to measure full spectra. The measurement system may be particularly useful in a process control environment where it is desirable to take measurements of one or more substances in different locations.

    摘要: A system includes a signal source that provides a first signal for measuring a gas content of a liquid sample. The system also includes an analyzer that determines the gas content of the liquid sample using a measurement of a second signal, where the second signal is based on the first signal. The system further includes an apparatus with a walled structure having a cavity. The apparatus also includes a piston that pulls the liquid sample into the cavity and pushes the liquid sample out of the cavity. The apparatus further includes at least one measurement window having at least one inner surface exposed within the cavity. The at least one measurement window receives the first signal from the signal source and provides the second signal to the analyzer. The piston could also clean the at least one inner surface, and the piston can include a reference material for calibrating the analyzer.
