Abstract:

With time going on and instrumental analytical techniques progressing, the health effects of common trace
elements (for example As, Hg and Se) have gained more attention. As an increasing number of ‘exceeding standard’
incidents occur, the development of analytical techniques for element speciation studies is of great significance. Hyphenated
analytical techniques enabling highly efficient separation and highly sensitive detection are the inevitable trend of element
speciation analysis. The aim of this article is to review modern hyphenated instrumental techniques with sample pretreatment
procedures for element speciation analysis. The advantages and disadvantages of various analytical techniques and the future
prospects of element speciation analysis are also discussed aiming to provide sufficient references for the choice of analytical
methods for element speciation analysis.

Key words: hyphenated techniques, speciation analysis, pretreatment, separation, detection
