Miniaturization of Analytical SystemsPrinciples, Designs and Applications
The book describes a general vision of the miniaturization of the analytical systems, including their principles, designs and applications. Through ten chapters the different aspects characterizing the miniaturized systems are developed. Thus, the two first chapters include the basic concepts behind miniaturization in analytical chemistry, as well as the mechanical and electronic tools needed for designing and fabricating miniaturized analytical systems. Chapters 3 to 6 represent the core of the book, as they take as the basis the analytical process and deal with the miniaturization of sample treatment (including the consequent automation), with sections devoted to the problems associated with sample introduction in micro(nano) systems; miniaturized systems for analyte separation, depending of the forces involved in moving the flow; and detection in micro-size environments. Following on, Chapters 7 and 8 will deal with the miniaturization of the entire process: from sample introduction to the generation of the corresponding analytical results. The last part of the book will deal with two aspects of miniaturized analytical systems directly connected to their usefulness: the design of portable miniaturized systems (interesting for performing field tests) and how to assure the practical reliability of the micro(nano) systems (quality control tests, performance and validation activities, as well as the robustness of the miniaturized depicted systems. The ruggedness of micro(nano) systems are briefly discussed and related to the tools for designing and fabricating described in the first chapters of the book.

"There is a good balance among the different topics dealt with as well as among the theoretical background, the description of the miniaturized systems and their practical applications. No doubt, the book will be very valuable for researchers, students and teachers of analytical chemistry because it represents the immediate future of this discipline." (Zentralblatt Math, 2010) "The authors have achieved a very nice mix of theoretical discussions and the use of equations, graphs and tables to make points and give comparisons. They also use photographs well and do no over-populate pages with photograph after photograph. Overall, they have made this into a readable book and also a good initial reference book." (Chromatographia, 22 January 2011) "The book is comprehensive and clearly written. There is a good balance among the different topics dealt with as well as among the theoretical background, the description of the miniaturized systems and their practical applications." (Analytical and Bioanalytical Chemistry, Jan - June 2010)
Modern analytical techniques aim to improve selectivity and sensitivity, achieve faster analysis time and increase throughput. These very ambitious goals are exacerbated by the need to reduce the overall size of the device and the instrumentation. The interest for portable analytical instruments, which allow field tests to be carried out easily, has increased the practical usefulness of miniaturized analytical systems. Miniaturization of Analytical Systems: Principles, Designs and Applications provides a highly needed general vision of the miniaturization of analytical systems, including their principles, design and applications. Included within this valuable text are: basic concepts behind miniaturization in analytical chemistry integrated classification of the miniaturized analytical systems and definition of the terms associated with miniaturization the mechanical and electronic tools needed for designing and fabricating such systems In addition procedures for both miniaturization and coupling to conventional equipment are systematically presented and discussed real applications and the analytical performance tests that can be established to assure the reliability of these microsystems are presented
