DGT Hg sampler separates mercury 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 Spheron-Thiol. The sampler 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.

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.

The deployment device holding and protecting PUF filter. Deployment canisters PAS protects PUF membranes from precipitation, UV sunlight, strong wind and particle deposition. The product consists of two bowls placed on the common axis, which fixes PUF filter in the proper position, hanging hook, nuts, pads, distance tubes. Passive samplers are hung at height around 1,5 to 2,0 m above ground. Suitable installation position is in open area without significant obstacles in order to allow for the free flow of air around the sampler.

The polyurethane foam for persistent organic pollutants (POPs) sampling in the air. The air streams freely around a filter, which captures pollutants during the period of passive air sampling. The sampling occurs through spontaneous diffusion of the analyte to the sorbent media – PUF. Subsequently, POPs are then analyzed in the PUF. PUF filter are at circular shape equipped with the metal insert. The duration of the sampling is usually 4 weeks or up to 3 months. PUF filter is precleaned and can be used immediatelly.
