被動式採樣裝置不需用外加能源及人為控制，適合長時間連續、大面積、荒野地區的環境樣品採樣。本文介紹四種被動式採樣器，包括半透膜採樣裝置、極性有機化合物累積採樣裝置、PUF 盤採樣器與擴散梯度薄膜採樣器。

Passive sampling devices are free of external power and human intervention requirements. They are suitable for long-time consecutive, large-area, and remote-area sampling of environmental samples. This paper introduces four passive sampling devices including semipermeable membrane device (SPMD), polar organic chemical integrative sampler (POCIS), polyurethane foam disk (PUF disk) sampler, and diffusion gradients in thin-fi lm (DGT) sampler.
