    Abstract: A photonic measurement system, such as an atomic absorption spectrometer, includes source, sample and detection modules that are interconnected by fiber optic cables. A first set of fiber optic cables guides light from one or more light sources in the source module to each of at least two analysis chambers in the sample module. A second set of fiber optic cables guides light from the analysis chambers to a detector in the detection module. The detector provides to a processing sub-system signals that correspond to intensities of the guided light. One analysis chamber is selected to perform a sample analysis at a given time, and the processing sub-system processes the signals associated with the selected analysis chamber as measurement signals. The processing sub-system may further process the signals associated with a given non-selected analysis chamber as reference signals.

    Abstract: A spectrometer is provided with an integrating sphere 20, inside which a sample S of a measurement target is disposed and which is adapted for observing measured light emitted from the sample S, and a Dewar vessel 50 which retains a refrigerant R for cooling the sample S and at least a portion of which is located so as to face the interior of the integrating sphere 20. Gas generated from the refrigerant R is introduced through predetermined gaps G1-G6 functioning as a gas introduction path and through a plurality of communicating passages 64 formed in a support pedestal 61, into the integrating sphere 20. The gas introduced into the integrating sphere 20 absorbs water in the integrating sphere 20 to decrease the temperature in the integrating sphere 20, so as to prevent dew condensation from occurring on a portion of a second container portion 50b of the Dewar vessel 50 exposed in the integrating sphere 20. This can prevent occurrence of dew condensation even in the case where the sample S is measured in a cooled state at a desired temperature.

    Abstract: Fusarium infected grain is separated by comparing reflected and transmitted light at two wavelengths, one at which the light is substantially reflected and scattered the same by healthy and infected kernels, the other at which the light is reflected and scattered to a significantly greater degree by infected than healthy kernels. An apparatus having a rotating apertured cylinder, with a low internal vacuum, allows comparison of individual kernels. When comparison indicates that a kernel is infected, a lever dislodges it from the cylinder allowing it to fall into a receptacle for infected kernels. Kernels remaining on the cylinder are scraped off to fall into a receptacle for healthy kernels. Although results vary, to some extent depending on the degree of infection, approximately 90% of healthy kernels and 5% of infected kernels are deemed “healthy”, while approximately 10% of healthy kernels and 95% of infected kernels are deemed “infected,” reducing the level of infected kernels.
