DGT is a passive sampler device for measuring pollutants, nutrients and other components, either in situ or in the laboratory. Products supplied for more than 25 years by DGT Research Limited have established DGT as a leading passive sampler, research and monitoring tool, used widely by scientists...

As a passive sampler, DGT makes it possible to perform in situ pre-concentration and to determine time-weighted average concentrations. Thanks to these characteristics, DGT is now considered as a potential monitoring tool for regulatory programs (Allan et al., 2008, Miège et al., 2012). The...

Metal behaviour and availability at a contaminated dredge material disposal site within UK waters has been investigated using Diffusive Gradient in Thin films (DGT) passive sampling technology. Three stations representing contrasting history and presence of maintenance dredge disposal, including a control ...

The passive sampling technique, diffusive gradients in thin films(DGT) has attracted increasing interests as an in-situ sampler for organic contaminants including per-and polyfluoroalkyl substances(PFAS). However, its effectiveness has been questioned because of the small effective sampling area(3.1 cm...
