ABSTRACT
The porous polymer stationary phases which for many years have been available in packed gas chromatography (GC) columns have only recently become available as a coated capillary. These cross-linked porous polymer columns are produced by copolymerizing styrene and divinylbenzene. The high-speed columns are generally used where highest efficiencies and speeds are required, such as GC-mass spectrometry (GC-MS) applications where reduced run times can increase source and electron multiplier lifetimes. Atomic spectroscopy as a means of detection in GC is becoming popular because it offers the possible selective detection of variety of metals, organometallic compounds, and selected elements. The basic approaches to GC-atomic spectroscopy detection include plasma emission, atomic absorption, and fluorescence. A statistical evaluation of methods using headspace GC for determination of ethylene oxide in plastic surgical items was performed by M. Kaye and T. Nevell. Two methods were evaluated: an external standard method using ethylene oxide in air, and an internal standard method using dilute aqueous solution with acetone.
