A light-scattering detection device includes a transparent sample cell, a light source for emitting coherent light onto the sample cell, an imaging optics for collecting scattered light from the sample cell to the periphery thereof at different scattering angles, a slit plate for limiting the scattering angle range, a detector for receiving collected light from the imaging optics, and an aperture plate for limiting, by the aperture width thereof, the width of the light received by the detector, the aperture plate being arranged in the detector with respect to the focal length of the imaging optics. A plurality of detection optics is arranged around the sample cell at equal intervals from the central axis of the sample cell. The aperture width of each aperture plate differs in accordance with the arrangement angle θ of each detector with respect to the sample cell.

Light-scattering detection device

Disclosed in a light scattering detection apparatus, including a sample cell for holding a liquid sample therein, a light source for irradiating the sample cell with coherent light, a detector for detecting light that coming from the sample cell, and a pair of holders for holding ends of the sample cell. Either or both of the holders has a double flange structure. The double flange structure includes a first flange configured to receiving the sample cell and a second flange configured to hold a tube connected to the sample cell. The second flange is detachably attached to the first flange.

Light scattering detection apparatus

To obtain a resin type identification method and a resin type identification apparatus with which an optimum infrared reflection spectrum for identifying a resin piece can be selected and accurate identification processing can be performed successively on individual resin pieces even when the resin pieces are identified using a single optical detector, at least one identifying signal power is selected by executing signal processing on the basis of signal powers corresponding to infrared reflection intensities obtained by emitting infrared light onto the resin piece, and the resin type of the resin piece is identified on the basis of an infrared reflection spectrum corresponding to the selected identifying signal power.
