Gas chromatography of metal chelates with carrier gas containing ligand vapour.
The vapour of the ligand was used as carrier-gas additive in the gas chromatography of metal chelates. The effect of trifluoro-acetylacetone on non-symmetrical peaks was examined for Be(TFA)(2), Al(TPA)(3) Cr(TFA)(3), Pe(TFA)(3), U(TFA)(4) and Th(TFA)(4). All the chromatograms appeared quite normally especially those of Th(TFA)(4); Fe(TFA)(3) and Th(TFA)(4) were improved markedly by using the carrier gas containing ligand vapour.
