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.
