摘　　要：超临界流体色谱（ＳＦＣ）在色谱分离过程中能在较低的温度下分析对热不稳定的化合物，包括金属络合物和金属有机化合物。本文总结了近来文献报道的各种过渡金属、重金属、镧系和系以及铅、汞和锡的金属有机化合物的ＳＦＣ分离，还讨论了ＳＦＣ检测系统和金属有机化合物的溶解度的测定。Supercritical fluid chromatography (SFC) combines the high diffusion coefficients of gas chromatography (GC) and the solubility properties of liquid chromatography (LC). SFC generally requires lower temperatures for chromatographic separations and thus is more suitable for analyzing thermally labile compounds including a number of metal chelates and organometallic compounds. 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 by SFC. This article summarizes SFC separation of various chelates of transition metals, heavy metals, lanthanides and actinides as well as organometallic compounds of lead, mercury and tin reported in the recent literature. This article also discusses SFC detection systems and the determination of solubility of organometallic compounds by SFC.
