Welcome to DGT® Research

DGT is a passive sampler device for measuring pollutants, nutrients and other components, either in situ or in the laboratory.

Products supplied for more than 20 years by DGT Research Limited have established DGT as a leading passive sampler, research and monitoring tool, used widely by scientists, agencies and industry. DGT passive samplers can measure metals and organic compounds and are routinely used to monitor water quality and assess soil and sediment contamination and processes. Manufacture is undertaken by a dedicated team in a purpose-built suite of clean laboratories, ensuring high standards of quality control.

New users of DGT are advised to use the Select Your DGT heading at the top of the page. This allows you to select the analytes or groups of analytes you wish to measure and guides you to the DGT product most suitable to your application. The particular DGT passive sampler can be added to your basket for purchase, but note that no payment is required until you are supplied with the goods.

Existing users might wish to select the DGT product they wish to use from the Products and Purchases section. This allows you to browse the full range of products, including DGT components.

Within What DGT Does you will find explanations of how DGT passive samplers work, information that enables automatic calibration, detailed guides to their use and useful references.

DGT® is a trademark which is registered throughout the world.

Beware of Poor Products

By |November 23rd, 2020|Categories: General|Comments Off on Beware of Poor Products

Although DGT is a registered Trademark there are unscrupulous companies which flout this and sell unlicensed products under the DGT name. Rather than using our well tested polyacrylamide gels made using a special crosslinker only available from DGT Research, they use agarose, even for multivalent cations and anions, including trace metals. It is well established that agarose gel is charged. In freshwaters, this causes DGT measurements of cations to be overestimated and of anions to be underestimated (see FAQ).

Peter Teasdale

It is with great sadness that we report the untimely, sudden death of Peter Teasdale on 7th August. Many in the DGT community will have fond memories of Peter. This warm and kind man played a leading part in expanding the role of DGT. With a strong sense of integrity he sought scientific truth, and yet he was always approachable and willing to give his time and expertise to help others.

His research group pioneered many new avenues for DGT. Just two examples are how Peter built on his early success of 2D imaging for sulfide, to develop several simple colorimetric methods for 2D imaging that enabled new insights into sediment processes. By developing alternative binding agents, most notably titanium dioxide for oxyanions, his group provided new in situ tools to begin to understand localised biogeochemical interactions. Peter’s work with industry and regulators promoted the practical use of DGT, greatly enhancing its impact beyond the world of research.

Peter was a loving family man and will be greatly missed by his wife Bernadette and their two daughters, Natalie and Katelyn. We will all miss him in so many ways.
