As everyone knows, the role played by extraction and sample preparation in the analytical sciences cannot be overemphasized. Despite tremendous advances in chromatography, detection, and other aspects of analysis, extraction and sample preparation remain a preanalysis ritual of critical importance. It has been estimated that around 50% to 70% possibly even more of the time and effort that goes into an analytical process comprises extraction and sample preparation. Sample preparation procedure can vary in the degree of selectivity, speed, and convenience, depending on the approach and conditions used, as well as on the geometric configurations of the extraction phase and conditions. Optimization of this procedure aids enhancement in the performance of the overall analysis. Proper design of the extraction devices and procedures facilitates rapid and convenient on-site implementation, coupled with separation/quantification and/or automation. We invite authors to submit research and review articles that seek sample preparation, analytical extraction, and sample clean-up techniques. It will be a perfect opportunity for researchers and analysts to submit articles in all areas of sample preparation and extraction, on application fields such as green chemistry, forensic, bioanalytical, natural products, food, flavor chemistry, biological, pharmaceutical, chemical, clinical, and environmental analysis.

Potential topics include, but are not limited to:

• New technologies and techniques
• Traditional and emerging techniques such as Solid Phase Extraction (SPE) and Microextraction (SPME), Stir Bar Sorptive Extraction (SBSE), Dispersive liquid-liquid microextraction (DLLME), and Liquid Phase Microextraction (LPME)
• Recent advances on sample preparation for green chemistry, forensic, bioanalytical, natural products, food, flavor chemistry, biological, pharmaceutical, chemical, clinical, environmental analysis
• Microfluidics/Lab-on-a-chip: new devices and techniques
• New developments in sensors and assays
• Automated analytical systems
