The analysis of haloacetic acids is accelerated using novel direct column heating technology. Applying the tenets of chromatography theory, the mathematical limits of an accelerated separation are investigated. While traditional air bath ovens experience an early limitation of column temperature ramp rates, a gas chromatograph with direct heating circumvents this constraint. Adjustments are made to the method in order to approach the mathematical projections. Theoretical and experimental results will be compared in context.
