Title: Reactive diffusive gradient in thin-film sampler and mercury speciation by use of same

Abstract

Sampling devices for mercury speciation protocols are described. Devices can be utilized to separate mercury species from one another as a sample diffuses through a sampling device. Methods can determine the presence or quantity of targeted mercury species in a fluid sample. The devices are passive sampling devices based upon diffusion gradient in thin film (DGT) passive sampling devices. Devices include a reactant component and a sequesterant component that selectively react with a targeted species and retain a species (or a reaction product of a species) of a sample flow. Remaining mercury species can optionally be captured downgradient, for instance at an ion exchange resin.
