Summary

The aim of this work was to study the utilisation of coordinative europium compounds as stationary phase additives in gas chromatography.

The following series of aliphatic nucleophilic compounds were used as solutes: n-alcohols, carboxylic acid methyl esters, ketones, ethers and 1-alkenes.

A correlation was established between the chromatographic retention values and the NMR chemical shift changes induced by interactions of the organic molecules with the europium chelate.

The agglomerate formation between the europium chelates and nucleophilic compounds involves changes in the NMR spectra and selective increases in the GC retention values when adding europium chelates to the stationary phases.
