Available in PDF, EPUB and Kindle. Book excerpt: The operational characteristics of several new solid state array detectors investigated in our laboratories have shown themselves to be highly suitable for application in analytical spectroscopy. The devices investigated to date are selected charge-coupled devices (CCDs) and charge injection devices (CIDs), each of which has certain unique capabilities which can be exploited for solving a variety of spectroscopic problems. Readout speed considerations when using sequential, pseudo-random, random, binning, and rapid scanning readout modes will be discussed. Optoelectronic characteristics of these devices including dynamic range, quantum efficiency, noise, resistance to blooming and lag will be contrasted to photodiode arrays, vidicons, and photomultiplier tubes. Several optical configurations for array detector spectrometers which effectively utilize the various device geometries including the latest generation echelle configuration will be presented. Design considerations including resolution, spectral coverage, detector element size, stray light, and image reduction will be discussed. Keywords: Optical spectroscopy; Multichannel techniques; Charge transfer devices.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Handbook of Green Analytical Chemistry written by Miguel de la Guardia and published by John Wiley & Sons. This book was released on 2012-02-23 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emerging field of green analytical chemistry is concerned with the development of analytical procedures that minimize consumption of hazardous reagents and solvents, and maximize safety for operators and the environment. In recent years there have been significant developments in methodological and technological tools to prevent and reduce the deleterious effects of analytical activities; key strategies include recycling, replacement, reduction and detoxification of reagents and solvents. The Handbook of Green Analytical Chemistry provides a comprehensive overview of the present state and recent developments in green chemical analysis. A series of detailed chapters, written by international specialists in the field, discuss the fundamental principles of green analytical chemistry and present a catalogue of tools for developing environmentally friendly analytical techniques. Topics covered include: Concepts: Fundamental principles, education, laboratory experiments and publication in green analytical chemistry. The Analytical Process: Green sampling techniques and sample preparation, direct analysis of samples, green methods for capillary electrophoresis, chromatography, atomic spectroscopy, solid phase molecular spectroscopy, derivative molecular spectroscopy and electroanalytical methods. Strategies: Energy saving, automation, miniaturization and photocatalytic treatment of laboratory wastes. Fields of Application: Green bioanalytical chemistry, biodiagnostics, environmental analysis and industrial analysis. This advanced handbook is a practical resource for experienced analytical chemists who are interested in implementing green approaches in their work.

Available in PDF, EPUB and Kindle. Book excerpt: Nanotechnology-based E-Noses reviews advances in nanomaterials and their modification for use in e-sensors. "E-noses" or "electronic sensors" are emerging as advanced technologies for the fast detection of chemicals, gases, and explosives. The concept behind the "e-nose" is similar to the capability of humans and dogs in detecting materials based on odors. Nanomaterials can be used for e-nose technologies but their properties must be modified to make them effective sensors. The sensing capability and performance of these materials depend on several factors, such as morphology, dopants, microadditives, design of sensors, phase, and structure of the nanomaterials. Theoretical understanding of nanomaterials and technologies for improving sensors with better detection limits are covered. The most relevant nanomaterials, their synthesis strategies, and the relationship between properties and device performance are provided. Current state-of-the-art progress in nanotechnology device fabrication along with directions for future applications and challenges are discussed. Covers fundamentals of nanomaterials for electronic sensing applications, including material synthesis and property optimization strategies to improve material performance Reviews emerging relevant nanomaterials including 1D, 2D and 3D nanomaterials for use in e-nose technologies Discusses nanotechnology-based e-noses and their wide range of applications in the detection of chemicals, gases, explosives, and more

Download or read book Spectrally Resolved Detector Arrays for Multiplexed Biomedical Fluorescence Imaging written by Anna Siri Luthman and published by Springer. This book was released on 2018-08-09 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the design, development, characterisation and application of two novel fluorescence imaging instruments based on spectrally resolved detector arrays (SRDAs). The simplest SRDA is the standard colour camera, which integrates a Bayer filter array of red, green and blue colour filters to replicate the colour sensing capability of the human eye. The SRDAs used in this book contain many more colours, ranging from 16 to over 100 colour channels. Using these compact, robust and low-cost detectors for biomedical applications opens new avenues of exploration that were not possible before, in particular, the use of spectral imaging in endoscopy. The work presented shows for the first time that not only can this new type of camera be used for fluorescence imaging, but also that it is able to resolve signals from up to 7 different dyes – a level of multiplexing not previously achieved in tissue with such compact and robust equipment. Furthermore, it reports the application of a bimodal endoscope performing both reflectance and fluorescence imaging using these cameras in an ex vivo pig oesophagus model.

Available in PDF, EPUB and Kindle. Book excerpt: Optical science and engineering affect almost every aspect of our lives. Millions of miles of optical fiber carry voice and data signals around the world. Lasers are used in surgery of the retina, kidneys, and heart. New high-efficiency light sources promise dramatic reductions in electricity consumption. Night-vision equipment and satellite surveillance are changing how wars are fought. Industry uses optical methods in everything from the production of computer chips to the construction of tunnels. Harnessing Light surveys this multitude of applications, as well as the status of the optics industry and of research and education in optics, and identifies actions that could enhance the field's contributions to society and facilitate its continued technical development.
