Book Description
This article is the first in a two-part series describing charge transfer devices (CTDs) -- a relatively new class of multichannel detectors for the ultraviolet to near-infrared spectral regions. An overview of the operation and the characteristics of CTDs relevant to analytical spectroscopy is presented. The sensitivity and dynamic range obtainable from CTD detectors are discussed and compared to the sensitivity and dynamic range obtainable from other spectroscopic detectors. Unique capabilities such as the ability to nondestructively readout the detector array and the ability to alter the effective detector element size using the process of binning are described. Detector array formats ranging from single elements to extremely large arrays, large photoactive areas, high quantum efficiencies, dark count rates allowing long integration times and low read noises all contribute to the outstanding performance and great flexibility offered by CTDs.

Book Description
This article is the first in a two part series describing the operation, characteristics and application of a new class of solid -state multichannel UV-visible detectors. In this manuscript, Charge Transfer Devices (CTDs) are described. Detector characteristics pertinent to spectroscopic application including quantum efficiency, read noise, dark count rate and available formats are emphasized. Unique capabilities such as the ability to non-destructively read out the detector array, and the ability to alter the effective detector element size by a process called binning are described. CTDs with peak quantum efficiencies over 80% and significant responsivity over the wavelength range of 0.1nm to 1100nm are discussed. Exceptionally low dark count rates which allow integration times up to many hours and read noises more than two orders of magnitude lower than commercially available PDA detectors both contribute to the outstanding performance offered by these detectors. Keywords: Spectroscopic detectors; Charge transfer devices; Charge coupled device; Charge injection device; OPtical spectroscopy.

Book Description
Because new information was discovered at an incredible rate since the publication of the successful first edition of this Handbook, this fully updated second edition covers all areas of interest in the field of capillary electrophoresis (CE). A relatively new technology, CE is a principle method for studying the physicochemical properties of proteins, peptides, and other macromolecules. Where applicable, the 30 chapters provide basic underlying theories as well as application-oriented aspects of each technique.Keep up with all the developments in this growing field with the Handbook of Capillary Electrophoresis, Second Edition - a complete guide to the fundamentals of CE and the latest research. The chapters are organized into five units: Modes: Presents a theoretical development of the basic principles governing separation with several modes, including CEC, and discusses their practical aspects. Analyte: Applies CE to the analysis of a specific class of analytes, including organic and inorganic ions, pharmaceuticals, glycoconjugates, peptides, proteins, and DNA fragments. Fundamental Aspects of CE: Technique-oriented information for the practitioner, including the importance of the sample matrix, on-line preconcentration of samples, modes of detection, and specific aspects of CE data analysis. Applications of CE: Includes single cell analysis, CE in DNA sequencing, CE as a clinical diagnostic tool, identifying and quantifying drugs, and for characterizing interacting species. Specialized Aspects of CE: Discusses interfacing CE with mass spectrometry, high-volume throughput continuous CE, microchip CE, control of EOF, and much more. The Handbook of Capillary Electrophoresis, Second Edition, pulls together diverse areas and applications of CE, resulting in an excellent tool for scientists involved in biotechnology and clinical chemistry, as well as the pharmaceutical, bioscience, chemical, and instrument-manufacturing industries. With an applications-oriented focus, the handbook is also a superb manual for workshops, seminars, and graduate courses in separation science.

Book Description
Recent investigations will be presented which demonstrate how new types of charge transfer device (CTD) array detectors can provide vastly superior performance to conventional approaches in a variety of optical spectroscopic applications. Operational characteristics of the two major classes of CTD's - charge coupled devices (CCD) and charge injection devices (CID) - will be briefly reviewed. Examples demonstrating the trade offs between the two classes of CTD's and their relative merits will be presented. Entirely new spectroscopic frontiers such as the 'Intelligent Atomic Emission Spectrometer' will be discussed. The ability to employ the vast amount of data available real time from a properly configured array detector can offer major advances in precision and accuracy. The concepts behind this approach, along with the advantages, will be presented. Keywords: Multichannel detectors, Charge injection detectors, Charge transfer devices, Electrooptical performance.

Book Description
This book provides the readers with the full basic knowledge necessary to understand, evaluate and develop critically any ETAAS analysis. The book covers comprehensively all aspects of the theoretical principles, routine and unusual instrumentation, overlapping possibilities with other techniques and different analytical characteristics of ETAAS at an averaged intermediate/high level. This is a good topic for a text book owing to the wide analytical possibilities of ETAAS in academic and industry laboratories. The book is written by a qualified expert with 30 years' experience working on different aspects of ETAAS.The work guides the readers through an in-depth descriptive appraisal of the chemical and physical processes occurring in an ET atomiser. The work compares favourably with other books already published on this subject as this work shows an overview with some different perspectives, focusing mainly on the processes taking place during an ETAAS analysis. An ordered, rigorous and deep description is found in every chapter. The book would be adequate for undergraduate and graduate students in any course of analytical chemistry, researchers in analytical atomic spectrometry and analysts who routinely use ETAAS. Amateurs and specialists in this field will find a good support in the book.
