Abstract:

The proper functioning of life is critically dependent on trace elements in a number of different ways. Some trace elements are highly toxic whereas others, considered essential, are needed for the accomplishment of life process. A surge of evidence during the past 20 years has been leading to the conclusion that it is not the total element content but that of a particular species that should be determined if valid information on the essentiality or toxicity of a given element is to be obtained[1-5]. Thus, speciation analysis has become one of the fastest developing areas of analytical chemistry towards the close of the 20th century[5]. The advantages of Capillary Electrophoresis include rapid analysis, low sample requirements, high separation efficiency and low operation costs[6]. The separation potential of CE,with superior detection capability of ICPMS make CE-ICPMS a powerful tool for metal speciation.
