Sample preparation is applied to make real world samples amenable for chromatographic analysis‎,‎ or to improve the results of this type of analysis‎.‎ A wide variety of procedures are applied for this purpose‎,‎ and their description is the main goal of the present book‎.‎ The principles of these procedures are explained‎,‎ discussing their advantages and disadvantages‎,‎ and their applicability to different types of samples as well as their fit for different types of chromatographic analysis‎.‎ This provides a guide for choosing the appropriate sample preparation for a given analysis‎.‎ The book also contains numerous literature references and examples of sample preparation for different matrices‎.‎ The material is presented in three parts‎,‎ one discussing physical methods used in sample preparation such as filtration‎,‎ distillation‎,‎ solvent extraction‎,‎ solid phase extraction‎,‎ electro‎-separations‎.‎ * presents in a systematic way numerous techniques applied for sample preparation for chromatographic analysis * provides an up to date source of information regarding the progress made in sample preparation for chromatography * describes examples for specific type of matrices‎,‎ providing a guide for choosing the appropriate sample preparation method for a given analysis
