The DGT sampler for detection of arsenic.

DGT As sampler separates arsenic from solution while it is deployed.  Accurate, quantitative measurement of ultra trace concentrations can be measured. This device accumulates trace elements on a binding agent after passage through a diffusion membrane layer. The binding agent is created by Fe-oxide compounds.  DGT can be deployed in streams, lakes, rivers or effluents and sampling is independent on flow. Exposition takes around 14-20 days depending on contaminated area.
