摘要： The invention generally relates to methods for analyzing a heterogeneous sample. In certain aspects, the invention provides methods that involve illuminating a heterogeneous sample including a target analyte with polychromatic light, receiving luminous data of the heterogeneous sample and the target analyte is received to a detector without splitting the polychromatic light into individual wavelengths and generating spectral data therefrom. The analysis can be conducted without reacting the target analyte with chemical reagents.

摘要： An automatic analyzer has a multi-wavelength light source that irradiates a reaction cuvette containing a liquid mixture of a sample to be analyzed and a reagent. A transmitted-light quantity detector detects the amount of light transmitted through the reaction cuvette and internal contents of the reaction cuvette. A single-wavelength light source irradiates the reaction cuvette with single-wavelength light; and a transmitted-light quantity detector detects the amount of single-wavelength light scattered from the reaction cuvette. A memory stores the results of the transmitted-light quantity detection and the scattered-light quantity detection; and the deterioration states of the single-wavelength light source, multi-wavelength light source, and reaction cuvette are determined in accordance with measurement results of cell blank measurements conducted on the reaction cuvette where a predetermined reference solution is stored to detect the amount of light transmitted through and the amount of light scattered from.

摘要： An active imaging system, which includes a light source and light sensor, generates structured illumination. The light sensor captures transient light response data regarding reflections of light emitted by the light source. The transient light response data is wavelength-resolved. One or more processors process the transient light response data and data regarding the structured illumination to calculate a reflectance spectra map of an occluded surface. The processors also compute a 3D geometry of the occluded surface.

摘要： A sample test method, microfluidic device, and test device efficiently and accurately compensates for interference of an interfering substance present in a sample using optical measurement without addition of a separate reagent for detecting the interfering substance. The sample test method includes: measuring an optical characteristic value of a target substance present in a sample; measuring an optical characteristic value of an interfering substance present in the sample; and determining a concentration of the target substance for which interference of the interfering substance is compensated for based on the optical characteristic value of the interfering substance.

摘要： Apparatus and methods to monitor contamination levels in a formation fluid are disclosed. An example method involves obtaining first property data indicative of a first fluid property of a formation fluid and second property data indicative of a second fluid property of the formation fluid. A correlation between the first and second property data is generated and third data is fitted to the correlation. A fitting parameter is determined based on the third data indicative of an amount of change of the first property data relative to an amount of change of the second property data.
