Abstract

Passive samplers have been widely used for volatile organic compounds determination. Following the green chemistry tendency of the direct determination of adsorbed compounds in membrane-based devices through using head space direct chromatography analysis, this work has evaluated the use of Amberlite XAD-2, XAD-4, and XAD-16 adsorbents as a filling material for passive samplers. Direct analysis of the membranes by HS-GC-MS involves a solvent-free method avoiding any sample treatment. For exposed membranes, recoveries ranged from 10% to 203%, depending on the compound and adsorbent used. The limit of the detection values ranged from 1 to 140 ng per sampler. Acceptable precision and sensitivity levels were obtained for the XAD resins assayed.

摘要

被动采样器已被广泛用于挥发性有机化合物的测定。为了顺应直接测定膜基装置中吸附化合物的绿色化学趋势，本工作评估了 Amberlite XAD-2、XAD-4 和 XAD-16 吸附剂作为被动采样器填充材料的用途。通过顶空直接色谱分析对膜进行直接分析，这种方法是一种无溶剂的方法，避免了任何样品处理。对于暴露的膜，回收率在 10%到 203%之间，具体取决于所用的化合物和吸附剂。每个采样器的检测值范围从 1 到 140ng。对所测定的 XAD 树脂进行了可接受的精密度和灵敏度水平的检测。
