Metal chelate polymers as selective sorbents for gas chromatography

Metal complexes of bis-β-diketonate ligands form polymers that are useful as selective sorbents for gas chromatography. The sorbents are capable of selectively retaining many oxygen- and nitrogen-containing compounds. The retained compounds can be desorbed for subsequent analysis by heating the meta...

Description
Summary:Metal complexes of bis-β-diketonate ligands form polymers that are useful as selective sorbents for gas chromatography. The sorbents are capable of selectively retaining many oxygen- and nitrogen-containing compounds. The retained compounds can be desorbed for subsequent analysis by heating the metal polymer. The sorbent properties of the complexes depend on both the metal and the ligand. Temperature also has an effect on the retention properties of the sorbents. It is possible to employ series of sorbents with different metal polymers. Application of such a series permits the conversion of a sample with a complex chromatogram into a set of samples with simpler chromatograms.
