介绍了一种测定浴池和公共水池中新型驱蚊剂贝避力的方法。通过固相萃取（SPE）或搅拌棒吸附萃取（SBSE）进行样品预富集。对富集物进行气相色谱-质谱（GC-MS）分析，两种提取方法对bayrel的检出限（LOD）几乎相同，均为25 ng L−1。由于所涉及的处理工作量略有减少，最终选择基于SBSE预富集的方法用于实际样品的分析。
A method for the determination of the new insect repellent Bayrepel in bathing lakes and public pools is presented. Sample preconcentration is performed either by solid-phase extraction (SPE) or stir bar sorptive extraction (SBSE). Analysis of the enriched analyte using gas chromatography-mass spectrometry (GC-MS) led to almost identical limits of detection (LOD) of 25 ng L−1for Bayrepel with both extraction methods. Because of the slightly reduced handling effort involved, the method based on preconcentration by SBSE was finally chosen for the analysis of real samples.
