Preparation of Polymeric Stationary Phase for Use in Inverse Gas Chromatography.

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 m2/cm3, 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.
