西兰花中13种有机含磷农药在不同色谱柱上的色谱保留行为

On the Retention Behaviors of 13 Residual Organophosphorus Pesticides in Broccoli on Different Chromatographic Columns in Gas Chromatography

摘要: 应用Agilent GC 6890气相色谱仪(附FPD检测器)对13种残留于西兰花中的有机含磷农药(OPP′s)在4种不同极性的毛细管色谱柱(即DB-1、DB-5、DB-1701及DB-35MS)上的保留行为作了研究。结果表明:采用由DB-5及DB-1701串联组成的色谱柱单元,西兰花中13种残留OPP′s可达到有效分离和测定。

Abstract: The retention of 13 organophosphorus pesticides (OPP′s) in broccoli on 4 capillary chromatographic columns with different polarities, namely DB-1, DB-5, DB-1701 and DB-35MS was studied using the gas chromatograph Agilant GC 6890 with FPD detector. As shown by the experimental results, by combining use of the DB-5 and DB-1701 columns in series, residues of the 13 OPP′s in broccoli were effectively separated and determined.
