Quality and reliability are central to success in every discipline, but perhaps nowhere are they more important or more interconnected than in the practice of analytical chemistry. Here, although reliable analytical information implies quality, not all "quality" information proves reliable.Quality and Reliability in Analytical Chemistry examines the various factors affecting these parameters in each step of the analytical process:The Sample: Investigate the reliability of the sample, including its history and homogeneity.The Method: See the connection between reliability and the selection of analytical methods for environmental, food, and clinical analyses.The Instruments: Examine the relationship between reliability and your instrumentation.Data Processing: Consider the importance of chemometrics in the reliability of data processing.Automation: Explore automation of the analytic process through discussion of its parameters - rapidity, reproducibility, flexibility, and reliability.Standards and Standardization: Understand how quality and reliability cannot be assured without using standards for measurement and how only reliable methods can be standardized.The goal of the analytic process is to obtain high quality information with high reliability. Quality and Reliability in Analytical Chemistry helps you meet that goal and thereby satisfy your quality assurance and quality control requirements.

Ion-Pair Chromatography (IPC) is a rapidly evolving method for difficult analyses of organic and inorganic ions and ionogenic, neutral, and zwitterionic compounds. The possibilities for this technology continue to grow as novel ion-pair reagents and strategies are introduced at an accelerated level. Compensating for a dearth in the literature, Ion-Pair Chromatography and Related Techniques details the basics and the evolution of this established and easily tunable technique and explains its influence on similar methods.Theoretical modeling to applicationProviding a thorough exploration of the multiplicity of interactions involved in an IPC system, this book emphasizes the progress from theoretical modeling to application. It explores the practical potential of IPC in the life science, medicine, pharmacology, forensic, food, and environmental sectors. It examines the upgrade of column technology and instrumentation to improve data quality and to increase sample throughput. The book also compares IPC to other instrumental methods of analysis and discusses the rising importance of the ion-pair concept in different analytical techniques.Future endeavorsIPC has the potential to have lasting impact in the field of chromatography.

Originating from models of biological neural systems, artificial neural networks (ANN) are the cornerstones of artificial intelligence research. Catalyzed by the upsurge in computational power and availability, and made widely accessible with the co-evolution of software, algorithms, and methodologies, artificial neural networks have had a profound impact in the elucidation of complex biological, chemical, and environmental processes. Artificial Neural Networks in Biological and Environmental Analysis provides an in-depth and timely perspective on the fundamental, technological, and applied aspects of computational neural networks. Presenting the basic principles of neural networks together with applications in the field, the book stimulates communication and partnership among scientists in fields as diverse as biology, chemistry, mathematics, medicine, and environmental science. This interdisciplinary discourse is essential not only for the success of independent and collaborative research and teaching programs, but also for the continued interest in the use of neural network tools in scientific inquiry.The book covers: A brief history of computational neural network models in relation to brain functionNeural network operations, including neuron connectivity and layer arrangementBasic building blocks of model design, selection, and application from a statistical perspectiveNeurofuzzy systems, neuro-genetic systems, and neuro-fuzzy-genetic systemsFunction of neural networks in the study of complex natural processesScientists deal with very complicated systems, much of the inner workings of which are frequently unknown to researchers. Using only simple, linear mathematical methods, information that is needed to truly understand natural systems may be lost. The development of new algorithms to model such processes is needed, and ANNs can play a major role. Balancing basic principles and diverse applications, this text introduces newcomers to the field and reviews recent developments of interest to active neural network practitioners.

Even a cursory perusal of any analytical journal will demonstrate the increasing important of trace and ultra-trace analysis. And as instrumentation continues to develop, the definition of the term "trace element" will undoubtedly continue to change. Covering the composition and underlying properties of freshwater and marine systems, Analytical Measurements in Aquatic Environments provides the basis for understanding both. It discusses all aspects of analytical protocols from the handling of representative samples to the metrological evaluation of specific steps and whole procedures. The book covers:handling of representative samplessample preservation techniquesextraction techniquesspeciation analyticssolvent-free sample preparation for analysisapplication of biotestsbioanalytical methods for monitoring green analytical chemistry-application of the concept of sustainability in analytical laboratoriesapplication of the Life Cycle Assessment approachquality control and quality assurance of analytical resultsenhanced techniques of sample preparationhyphenated analytical techniquesEcotoxicological considerations and the effort to achieve an increasingly accurate description of the state of the environment challenge analytical chemists who need to determine increasingly lower concentrations of various analytes in samples that have complex and even non-homogenous matrices. The newly coined expression "analytics" emphasizes the interdisciplinary nature of available methods for obtaining information about material systems, with many methods that exceed the strict definition of analytical chemistry. Drawing on the disciplines of chemistry, physics, computer science, electronics, material science, and chemometrics, this book provides in depth information on the most important problems in analytics of samples from aquatic ecosystems.
