ABSTRACT:
An apparatus for securing, analyzing and sorting materials, which allows such procedures as analysis and sorting of materials present as independent pieces at a high efficiency and a high accuracy, by securing individual pieces5of materials in receptacles4of a holder1at a definite posture using a light-hardenable adhesive at a uniform hardening strength and a uniform but brief hardening time by cold hardening under identical hardening conditions without causing denaturation of the material, wherein the receptacles4are arranged on the holder1in a definite arrangement and 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 uniformly form on each material piece an analyzing surface for which the analysis is performed. Each material piece5is bonded and fixed onto an inner wall of the receptacle4using a light ray-hardenable adhesive7by irradiating a light ray8thereonto to effect hardening of the adhesive at normal temperatures. The resulting holder1having the fixed material pieces is mounted on an analyzing unit12to subject each material piece to a spectrometric analysis by irradiating it with an electromagnetic ray15. Then, the holder1having the analyzed material pieces is set on a sorting device22to sort the analyzed material pieces, in which the material pieces are dispensed by operating dispenser rods24based on the analysis results.
