Available in PDF, EPUB and Kindle. Book excerpt: The renaissance of liquid chromatography took place in the late 1960's and early 1970's. The first edition of this book published in 1977 described the detectors that were available at that time and which provided a performance matching that of the contemporary equipment with which they were associated. It is interesting to note that the most popular detectors then (the UV detector, the refractometer detector, the fluorescence detector and the electrical conductivity detector) are still the most commonly used detectors nearly a decade later. Detector design, however, has changed very significantly over the intervening years. Modern high efficiency columns provide very narrow peaks and very fast separations, and thus the physical design of the detectors had to change to meet these new challenges. In 1977, there was little real understanding of the important role played by the detector in the overall function of the chromatographic system and although some of the factors were pointed out in the first edition of this book, in retrospect they appeared to be little understood.This second edition gives an entirely new presentation of the subject of liquid chromatography detectors. It contains sections dealing with the fundamental aspects of the interaction between columns and detectors and the interaction between ancillary equipment and the detector. It brings the reader up-to-date with new designs and novel detecting systems that have been developed since 1977 and extends significantly the subject of the association of the liquid chromatography detector with spectroscopic techniques. In particular the book now explores the association of liquid chromatography with nuclear magnetic resonance, infrared and atomic absorption spectrometry. This book not only gives a comprehensive treatment of the subject of liquid chromatographic detectors and provides a rational procedure for defining their performance and so permit valid comparisons, but also discusses detector performance in relation to the whole of the chromatographic system.

Book excerpt: The first book devoted exclusively to a highly popular, relatively new detection technique Charged Aerosol Detection for Liquid Chromatography and Related Separation Techniques presents a comprehensive review of CAD theory, describes its advantages and limitations, and offers extremely well-informed recommendations for its practical use. Using numerous real-world examples based on contributors’ professional experiences, it provides priceless insights into the actual and potential applications of CAD across a wide range of industries. Charged aerosol detection can be combined with a variety of separation techniques and in numerous configurations. While it has been widely adapted for an array of industrial and research applications with great success, it is still a relatively new technique, and its fundamental performance characteristics are not yet fully understood. This book is intended as a tool for scientists seeking to identify the most effective and efficient uses of charged aerosol detection for a given application. Moving naturally from basic to advanced topics, the author relates fundamental principles, practical uses, and applications across a range of industrial settings, including pharmaceuticals, petrochemicals, biotech, and more. Offers timely, authoritative coverage of the theory, experimental techniques, and end-user applications of charged aerosol detection Includes contributions from experts from various fields of applications who explore CAD’s advantages over traditional HPLC techniques, as well its limitations Provides a current theoretical and practical understanding of CAD, derived from authorities on aerosol technology and separation sciences Features numerous real-world examples that help relate fundamental properties and general operational variables of CAD to its performance in a variety of conditions Charged Aerosol Detection for Liquid Chromatography and Related Separation Techniques is a valuable resource for scientists who use chromatographic techniques in academic research and across an array of industrial settings, including the biopharmaceutical, biotechnology, biofuel, chemical, environmental, and food and beverage industries, among others.

Available in PDF, EPUB and Kindle. Book excerpt: This sixth volume in the book series Progress in HPLC-HPCE examines the enhancement of high- performance liquid chromatography through the development of an advanced mode of electrochemical detection (ECD) --- the coulometric array detection --- from its initial, yet problematic, amperometric (thin-layer) design to the highly sensitive, selective and stable coulometric (flow-through) design. Unlike amperometric electrodes, the coulometric electrode is 100% efficient and measures signals from all of the analyte passing through it, which leads to improved sensitivity as well as unique selectivity. The coulometric electrode array offers the resolution of the photodiode array with the extreme sensitivity of an electrochemical detector.

This book was released on 1980 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A potentiometric detector sensitive to many transition and rare earth metal ions has been developed, using a cupric ion-selective electrode. The sample stream is mixed with a stream of copper(II)-ethylene-diaminetetraacetic acid complex (CuEDTA), and metal ions in the eluent displace copper(II) from the complex. The increase in free copper(II) is then measured by the electrode. Background copper(II) level in the CuEDTA stream sets the lower limit of detection of metal ions at approximately 3X10-7th power M, and the detector response characteristics require that approximately 500micro l. flow through the detector to reach steady-state response. This establishes a detection limit of 1.5X10-10th power mole metal ion. Theoretical response of the detector has been developed and the experimental values agree closely with theory for specific metals over the range 3X10-7th power M to 10-2nd power M metal ion. Both transient and steady-state response of the detector to metal ions and some common anions, including halide ions, is shown, and the advantages and limitations of the system are discussed."--Abstract.

This book was released on 2012-12-06 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thin-layer chromatography (TLC) has become a common and much favoured separation technique in laboratories in widely varied fields in recent years. Much of the credit for the introduction of this technique into analytical practice at the l 2 end of the 1950s is due to E. Stahl • • This method is simple and is characterized by high separation ability and sufficient sensitivity3; however, some analysts feel that it has passed the peak in its development and will gradually be replaced by the more modem high-performance liquid chromatography (HPLC). This is undoubtedly a very important analytical technique utilizing the specific separa tion properties of a large number of sorbents and the possibility of regulating 4 the flow-rate of the mobile phase by adjusting the pressure • Standardization of the experimental conditions is simpler in HPLC than in TLC, where the activity of the sorbent and flow-rate of the eitlent in the thin layer depend markedly on the relative humidity of the laboratory atmosphere and on the composition of the gaseous phase in the elution chamber. In addition, systems for quantitative detection of the separated ~ones are better developed for HPLC than for classical TLC, where, until recently, cumbersome and often even insufficiently reproducible chemical or gravimetric analysis of the extracts of scraped-off spots or densitometry of the separated zones, located first by pyrolysis or reaction s with suitable detection agents, were the predominant determination methods .
