Abstract：Supercritical fluid chromatography (SFC) combines the hig h diffusion coefficients of gas chromatography (GC) and the solubility propertie s of liquid chromatography (LC). SFC generally requires lower temperatures for chromatographic separations and thus is more suitable for analyzing thermally l abile compounds including a number of metal chelates and organometallic compound s. SFC also allows interfacing between supercritical fluid extraction (SFE) and chromatographic analysis of metal-containing compounds. A large number of metal chelates and organometallic compounds can be separated b y SFC. This article summarizes SFC separation of various chelates of transitio n metals, heavy metals, lanthanides and actinides as well as organometallic comp ounds of lead, mercury and tin reported in the recent literature. This articl e also discusses SFC detection systems and the determination of solubility of or ganometallic compounds by SFC.
Keywords：Supercritical fluid chromatography, metal chelates, orga nometallic compounds, review
