Abstract

Described herein are passive samplers, making of such samplers, and methods of use. In an example embodiment, a passive sampling membrane comprises, for example, a continuous mesoporous sequestration media having a sequestration phase and a support membrane configured to support the sequestration phase. The sequestration phase may include a hydrophobic region and a hydrophilic region. The continuous mesoporous sequestration media may be configured to simultaneously sequester polar and non-polar organic substances.
