On the based of the qualitative and quantitative analysis to the recovered solution with gas chromatography, the experiments for recycling recovered.
对较低真空条件下的回收液进行气相色谱定性定量分析，在此基础上尝试了回收液的直接循环使用实验。

Compared with the chromatography, the resolution of the difficult separated compounds was enhanced by the recycling HSCCC.
结果表明循环逆流色谱法大大提高了难分离物质的分离度。
