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
