Analytical Microextraction Techniques by M. Valcárcel,S. Cárdenas,R. Lucena Pdf

Sample treatment has been the focus of intensive research in the last 20 years since it still remains a bottleneck in precise analytical procedures. The low concentration of the target analytes, the large amount of potential interfering agents and the incompatibility of the sample matrix with the instrumental techniques are the main reasons for these bottlenecks. In most of these methods, sample treatment is an unavoidable step and it has a clear influence on the quality (sensitivity, selectivity, and accuracy) of the final analytical results. While the usefulness of microextraction techniques has been established, their complete acceptance in analytical laboratories (including official methods of analysis) depends on their successful automation and integration with conventional analytical instrumentation. Analytical Microextraction Techniques presents comprehensive information about several analytical methods that are useful in the laboratory. These include: sorptive microextraction, solid and liquid phase microextraction, packed sorbent microextraction, miniaturized dispersive solid-phase extraction, thin film and nanoparticle based techniques, and membrane-based techniques. This is a vital reference on microextraction and sample preparation techniques for applied chemistry students, analytical chemists and laboratory technicians.

Sample Preparation in LC-MS Bioanalysis by Wenkui Li,Wenying Jian,Yunlin Fu Pdf

Revised and Expanded Handbook Provides Comprehensive Introduction and Complete Instruction for Sample Preparation in Vital Category of Bioanalysis Following in the footsteps of the previously published Handbook of LC-MS Bioanalysis, this book is a thorough and timely guide to all important sample preparation techniques used for quantitative Liquid Chromatography–Mass Spectrometry (LC-MS) bioanalysis of small and large molecules. LC-MS bioanalysis is a key element of pharmaceutical research and development, post-approval therapeutic drug monitoring, and many other studies used in human healthcare. While advances are continually being made in key aspects of LC-MS bioanalysis such as sensitivity and throughput, the value of research/study mentioned above is still heavily dependent on the availability of high-quality data, for which sample preparation plays the critical role. Thus, this text provides researchers in industry, academia, and regulatory agencies with detailed sample preparation techniques and step-by-step protocols on proper extraction of various analyte(s) of interest from biological samples for LC-MS quantification, in accordance with current health authority regulations and industry best practices. The three sections of the book with a total of 26 chapters cover topics that include: Current basic sample preparation techniques (e.g., protein precipitation, liquid-liquid extraction, solid-phase extraction, salting-out assisted liquid-liquid extraction, ultracentrifugation and ultrafiltration, microsampling, sample extraction via electromembranes) Sample preparation techniques for uncommon biological matrices (e.g., tissues, hair, skin, nails, bones, mononuclear cells, cerebrospinal fluid, aqueous humor) Crucial aspects of LC-MS bioanalytical method development (e.g., pre-analytical considerations, derivation strategies, stability, non-specific binding) in addition to sample preparation techniques for challenging molecules (e.g., lipids, peptides, proteins, oligonucleotides, antibody-drug conjugates) Sample Preparation in LC-MS Bioanalysis will prove a practical and highly valuable addition to the reference shelves of scientists and related professionals in a variety of fields, including pharmaceutical and biomedical research, mass spectrometry, and analytical chemistry, as well as practitioners in clinical pharmacology, toxicology, and therapeutic drug monitoring.

Green Sample Preparation Techniques by Chaudhery Mustansar Hussain,Javier Hernandez-Borges Pdf

There is a trend in analytical chemistry towards development of eco-friendly methods of sample preparation without loss of efficiency. This book provides a general, critical, and updated vision of the different green sample preparation approaches that have been developed. These include miniaturisation of the extraction techniques that allow a reduction not only of the chemicals used during the process, but also of the sample amount; the use of greener solvents, such as certain ionic liquids (ILs) or deep eutectic solvents (DES), instead of conventional organic solvents; and the use of new selective sorbent materials that allow both extraction and clean-up in the same step. All of these strategies have been successfully applied to the determination of a wide variety of organic and inorganic compounds. Advanced undergraduate and graduate students will find this book a good reference source and, because of the multidisciplinary nature of this topic, it will be of use to a broad audience including chemists, materials scientists, environmental analysts, forensic scientists, pharmacists, biologists and chemical engineers, who are involved and interested in the future frontiers of analytical chemistry.

Techniques to Measure Food Safety and Quality by Mohidus Samad Khan,Mohammad Shafiur Rahman Pdf

This book addresses the basic understanding of food contaminants and their sources, followed by the techniques to measure food safety and quality. It is divided into four parts: Part A - sources of contaminants in foods, their associated health risks, and integrated management and alternative options to minimize contaminants; Part B - Technological assessment of conventional methods and selected advanced methods for the detection, identification and enumeration of microbial contaminates; Part C - Technological assessment of different chemical measurements techniques; and Part D – Technological assessment of different instrumental techniques to assess sensory properties of foods. Food safety is a growing concern due to the increase in food-borne illnesses caused by food adulteration, excessive use of pesticides, use of chemical preservatives and artificial fruit ripening agents, microbial contaminations, and improper food handling. Chemical contaminants in food could be transferred from environmental or agrochemical sources, personal care products, and other by-products of water disinfects. In addition, microbial food safety can be threatened due to the presence of many pathogens, such as Salmonella, Escherichia coli, Clostridium botulinum, Staphylococcus aureus, and Listeria monocytogenes in foods. Globally, strict regulations are imposed to limit the potential contaminants in foods. Development of accurate, rapid, and inexpensive approaches to test food contamination and adulteration would be highly valued to ensure global food safety. There are existing processes to ensure safety of food products from chemical and microbial contaminants. Apart from the existing measurement technologies, varieties of new techniques are also being emerged and these could be potential to ensure food safety and quality. In addition to chemical and microbial properties, sensory properties such as texture, mouth feel, flavor, and taste, are among the most important attributes of food products to ensure their acceptability by consumers. Two approaches are available to evaluate sensory properties of food products, namely subjective and objective analyses. The responses are perceived by all five senses: smell, taste, sight, touch, and hearing. The approach used in sensory evaluation varies depending on the types of foods and the ultimate goal of the testing. Sensory attributes are the most important quality parameters after ensuring the safety of foods.
