| 中文摘要: |
| 介绍了凝胶色谱法的基本原理和工作方式及其在农药残留分析中的应用，对比了传统的全自动凝胶色谱和在线凝胶色谱-质谱联用两种凝胶色谱仪的特点。通过土壤样品有机磷和有机氯农药加标回收试验，表明两种凝胶色谱在农药残留分析中的净化效果差异不大，而在线凝胶色谱-质谱联用在检测快速化、在线化和溶剂使用少量化、微量化方面更具优势。 |
| 英文摘要: |
| Basic principle and working of GPC as well as application for pesticide residues analysis were briefly described. Characteristics of traditional GPC and online GPC/MS were compared. The results of recovery tests showed no obvious differences between traditional GPC and online GPC/MS. Fast online detection and small volume of solvent would be competitive for online GPC/MS in the monitoring analysis. |
