Each species has different chemical and biological behaviors. Toxicity is often dependent on it. So element speciation is important in a variety of environmental, biological, geological, and medical applications. Recently, capillary electrophoresis(CE) has been applied to speciation analysis owing to its high efficiency and short analysis time. This paper reviews the applications of CE-UV and CE-ICP-MS in speciation analysis and discusses some related problems.

D001151 Arsenic A shiny gray element with atomic symbol As, atomic number 33, and atomic weight 75. It occurs throughout the universe, mostly in the form of metallic arsenides. Most forms are toxic. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), arsenic and certain arsenic compounds have been listed as known carcinogens. (From Merck Index, 11th ed) Arsenic-75,Arsenic 75
D012643 Selenium An element with the atomic symbol Se, atomic number 34, and atomic weight 78.97. It is an essential micronutrient for mammals and other animals but is toxic in large amounts. Selenium protects intracellular structures against oxidative damage. It is an essential component of GLUTATHIONE PEROXIDASE. Selenium-80,Selenium 80
