Adsorption column assembly

Abstract

The present disclosure aims to provide an evaluation method for polyarylene sulfide resins that can uniformly quantify the surface properties of the polyarylene sulfide resin, thereby exhibiting less variability and more uniform reactivity compared to conventional evaluation methods. [Solution] The present disclosure provides an adsorption column assembly comprising a cylindrical body and a carrier containing a polyarylene sulfide resin filled inside the cylindrical body, characterized in that the zeta potential of the surface of the carrier is -50mV or higher.
