%X In this work, a novel support for apheresis application is presented which is based on microporous particles that were prepared from poly(ether imide) by a spraying/coagulation process. The polymer solution is sprayed through a hollow needle to form droplets and the droplets were vitrified by a nonsolvent induced phase separation. Results of the investigation of the spraying step and of the phase inversion step as well as characteristic data of the prepared particles are presented. Data of the particle characteristics verify that this technique is suitable to prepare highly porous support particles, which have a high accessibility of their internal pore system.
