　　Nickname: Polyvinylbenzene porous sphere-401; Polymer porous ball GDX-401

　　English name: Polyvinylbenzene porus beads-401

　　Chemical properties: milky white porous microspheres. It is a polymer formed by copolymerization of divinylbenzene and nitrogen-containing heterocyclic monomers. It has good thermal stability, corrosion resistance, and radiation resistance. Medium polarity, slightly alkaline.

　　Usage: Polymer porous microspheres (GDX series) are a new type of organic synthesis stationary phase (copolymerization of styrene and divinylbenzene), with medium polarity in gas chromatography (maximum operating temperature of 250 ℃), suitable for the separation of trace amounts of water in hydrogen chloride, formaldehyde aqueous solution, methanol, and water in lower grade amines.

　　Product characteristics: (1) Large specific surface area; (2) Uniform pore size distribution; (3) Regular shape and uniform particle size; (4) High mechanical strength, not easily crushed during processing.
