The preparation of ground low-density poly(ethylene) (LDPE), high-density poly(ethylene) (HDPE), and poly(ethylene terephthalate) (PET) materials suitable for use by inverse gas chromatography (IGC) experiments is described. Materials prepared showed a smaller and more uniform particle size, 83-86 µm (200 mesh), than commercially available Chromosorb ® W solid chromatography support. In addition, the BET surface area of polymeric materials, 0.367-0.559 m 2 /cm 3 , was much greater than the surface area of 150- to 212-µm-diameter glass beads. The use of polymeric materials with uniform particle sizes and defined surface areas have several advantages over polymer coated Chromosorb ® W and glass beads in IGC experiments.
