    Abstract: Provided is a chemical analysis device to analyze a chemical composition of a sample, including a main body including a laser light source, a chemical analysis unit, and a housing; an optical head that is arranged to be faced to the sample; and a pressureproof-feedthrough-equipped fiber that is extended from the housing to the optical head to guide laser light emitted from the laser light source to the optical head. The housing houses the laser light source and the chemical analysis unit as having a pressure-resistant function. The optical head includes a mirror system that causes the sample to be irradiated with laser light outgoing from the pressureproof-feedthrough-equipped fiber and to cause plasma emission light occurring at the sample owing to irradiation with the laser light to reenter to the pressureproof-feedthrough-equipped fiber. The chemical analysis unit performs spectroscopic analysis on the plasma emission light that reentered to the pressureproof-feedthrough-equipped fiber.

    Abstract: A method and apparatus for dating a dating a body sample, such as blood, includes taking at least one spectroscopic measurement (37) of the sample at least two predetermined positions in the spectrum having spectral characteristics corresponding to at least two predetermined substances present in the sample that have a time varying relationship with each other. A measured relative concentration of each of the predetermined substances is then determined (41) from the measurement, and the measured relative concentrations of the two predetermined substances is compared (43) with a known variation of the relative concentrations of the two predetermined substances over time. A good fit of the measured relative concentrations to the known variation of the relative concentrations is then determined, so as to provide an indication of the age of the sample (44). Alternatively, instead of measuring the relative concentrations of each of the predetermined substances, the rate of change of the relative concentrations is determined.

    Abstract: A measurement system for use with fluorescent chemosensors has multiple stimulus light sources each coupled to at least one sensor. Multiple sensors each receiving light from a different light source connect to each of one or more photodetectors. A processing device drives the light sources in a time-division multiplexed manner, and reads the photodetector at an appropriate time for each sensor. The processing device calibrates the sensor readings and provides them in a way that is identified to the associated sensor.
