Hyphenated Techniques Applied To The Speciation Of Organometallic Compounds In The Environment
Résumé
This chapter discusses the wide array of hyphenated techniques, which illustrates the important technical progress made during the last decade. However, not one technique can substitute for all the others and they should be considered as complementary. If instrumental solutions can be considered satisfactory, very few are available commercially at present. The success of speciation information delivered is not only dependent on the instrumentation used. The growing demand for speciation analysis is still hampered by the cost of the solutions available and the sample through-put. In this respect, systems using on-line cryofocusing and chromatographic separation prior atomic spectrometry detection appear to be robust and sensitive, allowing a high sample through-out. Flow injection analysis is further elaborated. © 1993, Elsevier B.V. All rights reserved.
