The complexes formed in organic solvent, aqueous and micellar solution are injected into chromatographic system or the metal ions are injected into the eluent containing the chelating agent.
The selection of chromatographic column, flow rate of carrier gas, column temperature, solvent, sample size and the column ratio of sample and solvent were experimented.
并对色谱柱、载气流速、柱温溶剂、进样量等色谱条件的选择，以及试样与溶剂的体积比的选择进行了实验。
