Elemental Speciation

The toxicity or reactivity of an element is often governed by its specific chemical form. Elemental speciation measures the individual amount of these chemicals, such as methylmercury in tuna fish, rather than the total amount of mercury present in the sample.

Types of Speciation Analysis Available

Arsenic : Soils, sediments, waters, tissues (both proteinaceous and cellulose-based, i.e. animal and plant materials) and aquatic, Foods. Determinations are achieved using HPLC-ICP-MS or HPLC-ICP-OES, depending on the concentrations expected.

Mercury : Fish, Food, Sediments. All by HPLC-ICP-MS.

Selenium : Foods or environmental samples. Detection achieved using HPLC-ICP-MS.

Antimony : Soils. HPLC-ICP-MS, HPLC-ICP-OES.

Chromium (3) / Chromium (6): Sediments, Soils. Determinations are achieved using HPLC-ICP-MS or HPLC-ICP-OES.

Nitrates / Nitrites / Phosphates / Silicates: Waters, Soils, Sediments, Plant Tissues. Determinations achieved using a Skalar SanPlus SFA.
