LoginWhile elemental selenium and selenides generally have a low bioavailability, the inorganic selenium compounds selenite and selenite are highly toxic. This is one reason why selenium speciation analysis adds valuable information to many studies. In the field of ecotoxicology, selenium is a particularly interesting element due to the fact that there is a relatively fine line between essential and toxic selenium concentrations
Selenium is a nutritionally essential element for both humans and animals and naturally occurs in a variety of plants and foods.
Used in:
Selenium in soil, sediments and water and other environmental matrices can thus mainly be traced back to agricultural and industrial processes but also natural activities.)
ALS offer analysis of inorganic selenium compounds by IC-HG-ICPMS. Samples are analyzed by ion chromatography with post column hydride generation and detection by inductively coupled plasma mass spectrometry. The use of hydride generation provides significantly improved sensitivity and thus better reporting limits (LOQ). ALS has analytical methods for testing for inorganic selenium compounds for a variety of sample types:
ALS offers analytical packages including the main inorganic selenium forms:

ALS offers analysis of organotin compounds mainly by GC- ICP-SFMS (Gas Chromatography coupled with ICP-SFMS). The testing for organotin compounds is accredited for water, soil, sediment, sludge and biota but can also be offered for electronics, textiles, paper, pulp and more. ALS is also proud to offer our clients low LOQ testing of OTC compounds, down to 0.0002 mg/kg, or 0.2µg/kg, dry weight for solid samples.
