A survey of modern methods for the analysis of water samples by capillary GC is presented. The methods are classified as direct methods, where water sample is directly introduced into the GC system, and indirect methods, where water is eliminated prior to transferring the analytes to a column. The direct introduction is realized by on-column, loop-type, or programmed-temperature vaporized injection. Water elimination is based on liquid-liquid, solid-phase, and gas extractions.
