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.
