Q. Is the DIFS dynamic model available?
A. When a DGT passive sampler is deployed in a soil or sediment it continuously removes the analyte of interest from the immediately adjacent porewater. If [...]
A. When a DGT passive sampler is deployed in a soil or sediment it continuously removes the analyte of interest from the immediately adjacent porewater. If [...]
A: The simple answer is ideally yes, but there are other considerations. Because the DGT assembly is thin it does not contain a lot of oxygen [...]
A: In most situations, this problem can be solved by adding 100 – 150 μL of MQ/deionized water to the gel surface and waiting for 10 [...]
A: The concentrations and speciation of analytes should not change after they bind to the binding gels. Thus the DGT devices can be stored in well [...]
A: According to our quality tests, most binding gels (except precipitated ferrihydrite gel) and diffusive gels (except bis-acrylamide cross-linked polyacrylamide gel known as BPA) can be [...]
A: Yes you can. The basic DGT equation can be used. [...]
A: In most situations where DGT is deployed in water that is flowing or subject to convection currents the standard DGT equation is appropriate. cDGT [...]
A. The most comprehensive listing of diffusion coefficients of mainly inorganic substances appropriate for DGT measurements can be found in W. Davison and H. Zhang, Diffusion [...]
A. Deployments in water In principle DGT can be deployed for a wide range of times from a few hours to a few months and interpretation of [...]
