Selenium distribution in the Australian sector of the Southern Ocean. Abstracts from the SCAR Open Science Conference, Hobart, 12-14 July 2006., 2006 (Ref: 12605)
Category 3: Poster

Selenium is an essential micronutrient but its role in oceanic biology is relatively unknown. Whilst this essentiality has been shown in laboratory work for some marine phytoplankton … species, the concentration, chemical species and incorporation methods are unknown.

On-column ion-exchange preconcentration of inorganic anions in open tubular capillary electrochromatography with elution using transient-isotachophoretic gradients. 3. Implementation and Method development. Analytical Chemistry, 2002 (Ref: 10417)
Category 1: Peer-reviewed literature

A solid-phase extraction method based on an ion-exchange retention mechanism … has been used for in-line preconcentration of inorganic anions prior to … their separation by capillary electrophoresis (CE).

Modern preconcentration methods for the determination of selenium species in environmental water samples Trends in Analytical Chemistry, 2004 (Ref: 11979)
Category 1: Peer-reviewed literature

Modern methods of preconcentration are investigated with … regard to the determination of selenium species in natural … (especially ocean) waters. The low concentration of selenium … in surface waters means that it is often present at levels below the limits of detection (LODs)…
