Selenium applications

P S Analytical are experts in the determination and speciation of selenium, arsenic, mercury, antimony and other hydride forming elements.

We supply dedicated analysis systems for total selenium measurements as well as selenium speciation, as well as providing contract analytical services to clients worldwide.


Selenium is relatively rare in the environment. Careful monitoring of selenium is essential as not only is it an essentail element but it is also toxic.

Visit our all about selenium page for general information on selenium, its properties, and how it impacts on the environment.

Selenium in Water and Soils and other mediaMillennium Excalibur

The Millennium Excalibur is used routinely by laboratories worldwide for the determination of total selenium in various solid, liquid and gaseous sample types.

Applications range from environmental samples such as fresh water, soil, sea water, estuarine water, sludge, coal and grass to clinical samples such as blood and hair, to foods e.g. wheat, milk and baby food to industiral applications such as mine tailings, aluminium and zinc electrolytes.

For further information visit our application notes page for a list of published applications. If you require additional or information on a specific applications please complete our information request form.

Selenium Speciation

Speciation is important to monitor levels of individual species as the toxicity of certain elements depends very heavily on their physio-chemical form.

P S Analytical's Millennium Excalibur has been used by researchers worldwide to carry out Se speciation studies, its excellent sensitivity, linearity and selectivity make it an ideal tool for this work.
