摘要:

AbstractThis paper describes optimization details of an analytical method development of a hydride‐generation procedure for speciation of mercury(II), monomethylmercury cation, dimethylmercury, and diethylmercury using a heated quartz furnace with an atomic absorption spectrophotometer (AAS) as a detector. Typically a new analytical method is developed in steps such as the following: (1) determining analytes individually to confirm retention times and the lack of decomposition during the procedure; (2) comparing peak areas of all analytes as a function of quartz furnace temperature to optimize atomization for AAS detection; (3) conducting factorial experiments to determine which hydride‐generation reaction conditions are important in maximizing peak areas and which conditions interact with each other; (4) using the simplex optimization method to give final optimization of reaction conditions. These steps result in conditions that maximize optimized peak areas for analytes while minimizing experimental er

摘要:

AbstractThe development of analytical techniques for the determination of chemical species has been one of the growing features of the 1990s in analytical chemistry. The need for good quality control of these determinations has led the Measurements and Testing Programme (formerly the BCR) to organize series of interlaboratory studies in the field of speciation analysis over the last five years. The state‐of‐the‐art speciation analysis has been discussed in a first workshop in 1990 (Arcachon, France) and, at this stage, it was thought necessary to discuss the progress achieved and the trends which should be developed in the near future. A workshop on Trends in Speciation Analysis was therefore held in Rome in February 1994 which allowed recommendations to be made based round‐table discussions. This paper gives a summary of these recommendations in the field of organometallic speciation. Projects currently undertaken in the field of organometallic speciation within the M&T programme are also described. An outline of the programme and a list of the panel of experts participating in this workshop are given in the a
