Chapter 3. Conventional Gas Chromatography: Basic Principles and Instrumental Aspects

Abstract

In this chapter, the basic principles of retention, efficiency and resolution in gas chromatography with open-tubular columns are outlined. Column technology with a focus on stationary-phase chemistry for wall-coated open-tubular columns, and in particular stationary-phase characterization, is described. Common methods of sample introduction using hot vaporizing, cold on-column and programmed temperature vaporizer injectors are described, as well as options for detection using ionization-based, bulk property and optical detectors.
