For the automated analysis of gasoline components in water samples a gas Chromatograph equipped with a multifunction controller, an on-column autosampler and a data acquisition system was used. Use of retention indices improves the reliability of the identification. However, components which differ less than 0.7 index units could not be discriminated by the available acquisition software. Further improvements of retention indices with the described equipment are not possible. Improvement of the GC-equipment is less important. A more accurate retention time registration is necessary. Control runs with GCMS are recommended. Pattern recognition techniques could be helpful to avoid serious mistakes in identification and quantitation.
