“…The continued rapid growth in interest in speciation, since the first edition of this book was published, is evidenced by the holding of the '1st International Conference on Trace Element Speciation in Biomedical, Nutritional andEnvironmental Sciences' in Neuherberg, Germany, in 1998 (Michalke andSchramel, 1999a) and, for example, by the formation, in 1997, of an 'EU-network on trace element speciation: preparing for the 21st century' (Cornelis et al, 1999) under the auspices of the Standards Measurement and Testing Programme.…”

“…5 An earlier, less ambitious initiative was the Thematic Network ''Speciation'21'' which was funded by the EC Standards, Measurements and Testing Programme over the period 1998-2000. 6 The solution of many problems of elemental speciation requires the determination of the chemical and physical behaviour and their interactions in different biogeochemical systems in addition to determinations in one particular phase of the environment. Especially determinations in solid matrices are becoming of growing importance for environmental and health application and for various applications in materials science.…”

The present day status of elemental speciation is largely based on the use of hyphenated techniques in particular in the combination of various types of chromatography with inductively coupled plasma mass spectrometry. The present status of environmental speciation with the hyphenated techniques is reviewed. There is a growing need for more comprehensive approaches including the direct analysis of solid samples especially for the elemental speciation of heterogeneous materials with microscopic methods of analysis. Methods for solid-state speciation analysis with several types of beam methods of analysis are critically discussed and are illustrated with two examples of our laboratory experience.

“…16,17 Determination of the species at a reasonable cost will be essential for the future development of the area, because the industry will be forced by legislation or quality control requirements. 18,19 The simultaneous multielement graphite furnace AAS determination will become more common in the future too, as a consequence of the ease of operation and increasingly large throughput of these methods. 16,20 Some years ago, we performed copper fractionation in milk binding proteins of high relative molecular mass by SEC and ETAAS using a Protein Pak glass 300 SW column, 30 cm 3 8 mm, Waters (USA) and a mobile phase with a 0.1 M phosphate buffer (pH = 6.7), 0.1 M ammonium nitrate (NH 4 NO 3 ) and 0.05% sodium azide (NaN 3 ).…”

This method will allow the determination of bound copper to low relative molecular mass compounds in milk. The milk whey obtained by ultracentrifugation was submitted to fractionation by size exclusion chromatography (SEC) on a TSK-Gel2000 (Toso Haas) column with a mobile phase of 0.2 M NH4NO3 + NH3, pH 6.7. Fractions of effluent corresponding to the protein peaks were collected and the copper content was determined by ETAAS. The method was sensitive (LOD 0.4 microgram l-1 and LOQ 1.5 micrograms l-1 in the fraction; LOQ 7.5-22.5 micrograms l-1 referred to the milk sample and depended on fraction volume) and precise (RSD +/- 10%). Media sample recoveries from the column were 101.2%. Cu was predominantly present in fractions corresponding to relative molecular mass 76 and 15 kDa of breast milk while copper was mostly found in fractions corresponding to 14 and 38 kDa of cow's milk-based infant formulae; moreover, copper was eluted in the relative molecular mass region < 6 kDa.
