Chromalite PCG1200MHEMA is a porous adsorbent, copolymer of hydroxyethyl methacrylate (HEMA) with divinylbenzene. Chromalite PCG1200MHEMA is a multi-purpose adsorbent, hydrophilic, water-wettable polymer with a unique hydrophilic-lipophilic balance. The adsorbent is wettable without methanol washing due to the presence of hydroxy groups (HEMA). The particle size 50-100 micron makes this polymer optimal for solid phase extraction.
