To provide an analytical method and an analyzer for a plasticizer in resin capable of easily performing a screening analysis on the plasticizer such as phthalic ester, etc. in resin samples with high sensitivity.
An analytical method for a plasticizer in resin includes: an evaporation step for evaporating a plasticizer from resin samples by heating the resin samples containing the plasticizer; a collecting step for condensing the plasticizer evaporated from the resin samples on a flat plate arranged in a manner to face the resin samples, so as to collect the plasticizer; and a concentrating step for dropping the solvent on a flat plate where the plasticizer is collected, wet-spreading the solvent on the flat plate, and concentrating the plasticizer at a periphery of the wet-spreaded solvent.
