P
S Analytical are experts in the determination and speciation
of arsenic, mercury, selenium and other hydride forming elements.
We
supply dedicated analyser systems for total arsenic measurements and for arsenic
speciation, as well as providing contract analytical services
to clients
worldwide.
Arsenic
Arsenic occurs in large quantities in the earth's crust and in trace quantities in rocks, soil, water and air. Exposure to high levels of arsenic can cause cancers and other disorders.
Visit our all about arsenic page for general information on arsenic, its properties, and how it impacts on the environment.
Arsenic in Water and Soils and other media
The Millennium Excalibur is used routinely by laboratories worldwide for the determination of total arsenic in a variety of liquid, solid and gaseous samples.
Applications range from environmental samples such as water, wastewater, groundwater, drinking water, sea water, soil, sludge, leaves, soil, food samples (e.g. rice, fish, chicken and other foodstuffs where bioaccumulation occurs) to industrial samples, including crude oil, aluminium, dyes, electrolytes and naphtha.
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.

Arsenic Speciation
Speciation is important to monitor
levels of individual species as the toxicity of certain elements
depends very heavily on their physico-chemical form.
P S Analytical's Millennium Excalibur has been used by researchers worldwide to carry out As speciation studies, its excellent sensitivity, linearity and selectivity make it an ideal tool for this work.
