Abstract

Three dimensional structures array were applied as LC columns. Two Menger-sponge-like 3D structures and their complementary structures were used as the arrayed structures. A separation based on the hydrophobicity was achieved after the surface modification with octadecyltrichlorosilane. Chromatographic performance was compared among four different structures. A structure with the largest void volume, a complementary structure of Menger-sponges-like 3D structure with a minimum pore of 150 × 150 μm2, showed the most suppressed mass transfer and the lowest pressure drop.
