    摘要： A system and method for using terahertz radiation to detect and monitor a substance undergoing a change in phase from a liquid phase to a solid phase or vice-versa is disclosed. By employing terahertz radiation in either the pulsed mode or in the continuous-wave (CW) mode, the system can non-invasively monitor these changes. The system uses the principle that matter in a liquid state will absorb and attenuate terahertz radiation to a larger degree than matter in a semisolid or solid state. Most terahertz radiation absorption occurs due to the rotational motions of molecules, i.e. either whole molecules or groups of atoms rotating about molecular bonds.

    摘要： The free fatty acid content of an edible oil is measured by a system (12). This system (12) includes a supply of a carrier solution (20) containing an organic solvent for dissolving the oil and a color indicating reagent. An oil sample (16) is supplied to a flow-through colorimetric detector (50) via a sample injection valve (36). The sample injection valve (36) is movable between a load position and a measured position. In the load position, a sample stream of the oil is routed to a sample waste collector (42) via a sample loop (38) and a stream of the carrier solution passes through the detector (50) via a carrier solution conduit (40). In the measure position, a slug of the oil in the sample loop (38) is introduced into the carrier solution conduit (40) and mixed with the carrier solution prior to passing through the detector (50).

    摘要： An apparatus for detecting a phase transition of a food sample includes: a support base for supporting a food sample which contains moisture and which is able to undergo phase transition between a solid and a liquid; a light penetration unit for permitting near-infrared light containing a light having a wavelength of absorption peak of water and a light having a wavelength of absorption peak of ice to penetrate into the food sample supported by the support base; a spectroscopic unit for dispersing the near-infrared light which is from the light penetration unit and which has transmitted and reflected in the food sample, and measuring a light intensity over a time; an absorbance-and-ice-weight-ratio calculation unit for calculating, on the basis of a spectroscopic data of the near-infrared light obtained by the spectroscopic unit, an absorbance of water and an absorbance of ice in the food sample and calculating an ice weight ratio with respect to a frozen moisture; an absorbance differential calculation unit for calculating a differential of the absorbance of water and a differential of the absorbance of ice which are calculated by the absorbance-and-ice-weight-ratio calculation unit; a calibration curve preparation unit for preparing a calibration curve on the basis of the differential of the absorbance calculated by the absorbance differential calculation unit and the ice weight ratio with respect to the frozen moisture calculated by the absorbance-and-ice-weight-ratio calculation unit; and an ice-weight-ratio estimation unit for estimating, on the basis of the calibration curve prepared by the calibration curve preparation unit, an unknown ice weight ratio from a differential of the absorbance calculated from the absorbance calculated by the absorbance-and-ice-weight-ratio calculation unit.
