Abstract
The analyte-detection power of gas chromatography combined with cryotr apping infrared spectrometry (GC-IR) is improved by a factor of 30-100 by injection of large sample volumes by use of a loop-type interface with concurrent solvent evaporation. The usefulness of this of the ana lysis of real-life samples is illustrated by the identification of pol yaromatic hydrocarbons (PAHs) in river Rhine water at a level of 0.5 m u g/l.
