10,000ug/mL SELENIUM 30mL

Selenium Expanded View


Location:  Group 16, Period 4
Atomic Weight:  78.96
Coordination Number:  6
Chemical Form in Solution:  H2SeO3

Storage & Handling:  Keep tightly sealed when not in use. Store and use at 20 ± 4°C. Do not pipet from container. Do not return portions removed for pipetting to container.

Chemical Compatibility:  Soluble in HCl, HNO3, H3PO4, H2SO4 and HF aqueous matrices and water. It is stable with most inorganic anions but many cationic metals form the insoluble selenites under pH neutral conditions. When fluorinated and/or under acidic conditions precipitation is typically not a problem at moderate to low concentrations.

Stability:  2-100 ppb levels stable for months alone or mixed with other elements at equivalent levels in 1 % HNO3 / LDPE container. 1-10,000 ppm solutions chemically stable for years in 1-5% HNO3 / LDPE container.

Se Containing Samples (Preparation & Solution):  Metal (soluble in HNO3); Oxides (readily soluble in water); Minerals and alloys (acid digestion with HNO3or HNO3 / HF); Organic Matrices (acid digestion with hot concentrated H2SO4 accompanied by the careful dropwise addition of H2O2 until clear).
