Apparatus and process for settling, analyzing and sorting materials, and sorted products

摘要

Apparatuses for settling, analyzing and sorting materials, which can afford to realize such procedures as analysis and sorting of materials present as independent pieces at a high efficiency in a high accuracy, by settling individual pieces 5 of materials in receptacles 4 of a holder 1 at a definite posture using a light-hardenable adhesive at uniform hardening strength in a uniform but brief hardening time by cold hardening under identical hardening condition without causing denaturation of the material, wherein the receptacles 4 are arranged on the holder 1 in a definite arrangement at a definite posture, whereby it is able to process each individual material piece after the hardening of the adhesive, by, for example, cutting and so on, to form uniformly on each material piece an analyzing surface for which the analysis is performed. Each material piece 5 is bonded and fixed onto inner wall of the receptacle 4 using a light ray-hardenable adhesive 7 by irradiating a light ray 8 thereonto to effect hardening of the adhesive at normal temperature. The resulting holder 1 having the fixed material pieces is mounted on an analyzing unit 12 to subject each mareial piece to a spectrometric analysis by irradiating it with an electromagnetic ray 15. Then, the holder 1 having the analyzed material pieces is set on a sorting device 22 to sort the analyzed material pieces, in which the material pieces are dispensed by operating dispenser rods 24 based on the analysis results.
