Sample preparation plays an essential role in analytical procedures. The estimated errors of measurement methods commonly used are usual below 20 per cent. The errors of sample preparation procedures can easily rise to more than 200 per cent. Relating to the total error of an analytical procedure it is more effective to invest efforts and money in the improvement of sample preparation techniques instead of squeezing the measurement procedures to get one or two percent improvement in standard deviation. This book is a concoction of chapters dealing with an overview of the latest developments in various sample preparation techniques for inorganic and organic analytes. Not only sample preparation techniques are described but also some sampling and measurement procedures.
O editor do livro é professor do Departamento de Química Analítica do Instituto de Química da Unicamp, e conta com 27 colaboradores, do Brasil e do exterior. O preparo de amostras é uma etapa importante em procedimentos analíticos, entre eles, as análises toxicológicas. O livro fornece uma visão geral dos últimos desenvolvimentos em técnicas de preparo de amostras para analitos orgânicos e inorgânicos. As diversas técnicas são apresentadas em oito capítulos: 1) Micro sampling for solid and slurries analytical methods; 2) Microwave-assisted procedures for sample preparation: recent developments; 3)Trends in sample preparation using combustion techniques; 4) Sample preparation of atmospheric aerosols for elemental analysis and fractionation studies; 5) Extraction and pre-concentration techniques for chromatographic analysis; 6) Strategies in sample preparation for applications in analytical electrochemistry; 7) In-line sample preparation in flow analysis; 8) The role of vanguard-rearguard strategies in sample preparation in routine analytical laboratories; 9) Strategies for sample preparation focusing on biomolecules determination/characterization.
