Food safety is a matter of great significance for the global population. Therefore, researchers have been developing and validating analytical methods to extract, separate and quantitate a variety of hazardous and nutritional analytes in various food commodities. Due to the complexity of food components, a suitable pretreatment method is required to eliminate matrix effects and lower the detection limit. Afterward, chromatography and mass spectrometry are powerful tools in the guarantee of food safety and quality. This book is the reprint of a Special Issue of Separations, “Advances of Accurate Quantification Methods in Food Analysis”, and provides an overview of recent trends in food analytical methods. Both novel sample pretreatment and detection techniques are covered, with the aim of accurate quantification. This Special Issue received nine contributions that covered the latest analytical methods, and focused on pesticides, mycotoxin, antibiotics, metal ions, organic selenium and anthocyanins.

Sample preparation is and will always be the most important step in chemical analysis. Numerous techniques, methods, methodologies, and approaches are published in the literature offering a wide range of analytical tools to the lab practitioner. Analytical scientists all over the world are trying to develop protocols for a plethora of analytes in various sample matrices. In the last decade, sample pre-treatment advances have followed green chemistry and green analytical chemistry demands, focusing on miniaturization and automation, using the least possible amount of organic solvents. The question is how far we have been till now, and what the future perspectives are. To answer this question, analytical chemists were invited to share their experience in the field and report on the recent advances in sample-preparation approaches. The outcome of our invitation was eleven excellent manuscripts, including four review articles and seven original research articles in the first edition of the Special Issue “Sample Preparation-Quo Vadis: Current Status of Sample Preparation Approaches”.The second edition is a collection of ten significant contributions to the field of sample preparation. It includes two highly interesting and comprehensive review articles and eight innovative research articles.

This book will provide the most recent knowledge and advances in Sample Preparation Techniques for Separation Science. Everyone working in a laboratory must be familiar with the basis of these technologies, and they often involve elaborate and time-consuming procedures that can take up to 80% of the total analysis time. Sample preparation is an essential step in most of the analytical methods for environmental and biomedical analysis, since the target analytes are often not detected in their in-situ forms, or the results are distorted by interfering species. In the past decade, modern sample preparation techniques have aimed to comply with green analytical chemistry principles, leading to simplification, miniaturization, easy manipulation of the analytical devices, low costs, strong reduction or absence of toxic organic solvents, as well as low sample volume requirements.Modern Sample Preparation Approaches for Separation Science also provides an invaluable reference tool for analytical chemists in the chemical, biological, pharmaceutical, environmental, and forensic sciences.
