DGT passive samplers equipped with an activated charcoal binding layer have been successfully used for the measurement of bisphenols A, B and F. The basic methodology and performance in waters is described in Zheng et…

An XAD18 binding agent has proved effective at measuring a range of antibiotics and we use it in our DGT passive samplers with a polyethersulphone filter membrane.  Some previous publications used HLB or XDA-1 as…

The potential capability of DGT for measuring polar organic compounds was recognised at its inception in the early nineties, but publications did not emerge until 2012. Since then, this capability has developed rapidly. A list…

Your selection indicates that you wish to measure both cationic and anionic substances. DGT passive samplers which use a mixed binding layer of Chelex and a metal oxide are capable of measuring simultaneously Al, Ca,…

The radionuclide Tc has been successfully measured with DGT using a specialist binding layer known as TEVA. DGT passive samplers equipped with this binding layer are available. For deployments in all types of waters you…

Sulphide is quantitatively accumulated on a DGT binding layer of AgI. The light yellow of the silver iodide changes to black as the sulphide accumulates. The resulting grey scale image allows simple quantification of sulphide…

Nitrate can be measured in freshwaters and soils using styrene divinylbenzene-based absorbent with amine functional groups (SIR-100-HP) as the binding phase. DGT passive samplers for these measurements are available. For deployments in fresh waters you…

While Cr(III) can be measured using the standard DGT passive sampler for cations with a Chelex binding layer, the oxyanion Cr(VI) cannot. A specialist binding layer of N-methyl-D- glucamine (DMDG) is required to measure Cr(VI)….

The binding agent 3-mercaptopropyl-functionalised silica gel selectively binds As(III) and excludes As(V). DGT passive samplers equipped with this binding agent are available for measuring As(III) selectively. For deployments in all types of waters you will…

Most anionic or neutral inorganic substances, which includes oxyanions, are best measured with DGT passive samplers that incorporate an oxide in the binding layer. The exceptions are: As(III), Cr, nitrate, sulphide or Tc. For advice…
