Download or read book Potential of Microbore HPLC (High Performance Liquid Chromatography) for Trace Organic Analysis in the Ocean written by Kenneth Mopper and published by . This book was released on 1986 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The adaptation of modern chromatographic techniques, especially capillary gas chromatography and high performance liquid chromatography (HPLC), to seawater analysis has lead to new insights into chemical and biological oceanographic processes. In this project the main long-range objective is to extend the role of HPLC by exploring the applicability of microbore HPLC to trace organic analysis of seawater. This technique offers substantially greater sensitivity and separation efficiency than conventional HPLC and, furthermore, the entire effluent of microbore columns may be fed into selective detectors, such as mass spectrometers and flame-base detectors. Initially, the microbore HPLC system will be used for the analylsis of carboxylic acids as part of our ONR-funded project. Other potential marine applications, such as the analysis of amino acids, pigments, photosensitizers, thiols, macromolecules and metal-organic complexes, will also be investigated as opportunities arise. In order to obtain information on the nature of the substances eluting off the microbore column the effluent will be analyzed spectroscopically with an on-the-fly UV-VIS diode array detector. Finally, we will explore potential marine application of laser excitation fluorescence detection in conjunction with microbore HPLC.

Book Synopsis Ultra-High Performance Liquid Chromatography and Its Applications by : Q. Alan Xu
Download or read book Ultra-High Performance Liquid Chromatography and Its Applications written by Q. Alan Xu and published by John Wiley & Sons. This book was released on 2013-04-01 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explores both the benefits and limitations of new UHPLC technology High performance liquid chromatography (HPLC) has been widely used in analytical chemistry and biochemistry to separate, identify, and quantify compounds for decades. The science of liquid chromatography, however, was revolutionized a few years ago with the advent of ultra-high performance liquid chromatography (UHPLC), which made it possible for researchers to analyze sample compounds with greater speed, resolution, and sensitivity. Ultra-High Performance Liquid Chromatography and Its Applications enables readers to maximize the performance of UHPLC as well as develop UHPLC methods tailored to their particular research needs. Readers familiar with HPLC methods will learn how to transfer these methods to a UHPLC platform and vice versa. In addition, the book explores a variety of UHPLC applications designed to support research in such fields as pharmaceuticals, food safety, clinical medicine, and environmental science. The book begins with discussions of UHPLC method development and method transfer between HPLC and UHPLC platforms. It then examines practical aspects of UHPLC. Next, the book covers: Coupling UHPLC with mass spectrometry Potential of shell particles in fast liquid chromatography Determination of abused drugs in human biological matrices Analyses of isoflavones and flavonoids Therapeutic protein characterization Analysis of illicit drugs The final chapter of the book explores the use of UHPLC in drug metabolism and pharmacokinetics studies for traditional Chinese medicine. With its frank discussions of UHPLC's benefits and limitations, Ultra-High Performance Liquid Chromatography and Its Applications equips analytical scientists with the skills and knowledge needed to take full advantage of this new separation technology.
Book Synopsis The HPLC Expert by : Stavros Kromidas
Download or read book The HPLC Expert written by Stavros Kromidas and published by John Wiley & Sons. This book was released on 2016-04-01 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid development of HPLC instrumentation and technology opens numerous possibilities - and entails new questions. Which column should I choose to obtain best results, which gradient fits to my analytical problem, what are recent and promising trends in detection techniques, what is state of the art regarding LC-MS coupling? All these questions are answered by experts in ten self-contained chapters. Besides these more hardware-related and technical chapters, further related areas of interest are covered: Comparison of recent chromatographic data systems and integration strategies, smart documentation, efficient information search in internet, and tips for a successful FDA inspection. This practical approach offers in a condensed manner recent trends and hints, and will also display the advanced reader mistakes and errors he was not aware of so far.

This book was released on 2018-06-15 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eight international laboratories specializing in the determination of marine pigment concentrations using high performance liquid chromatography (HPLC) were intercompared using in situ samples and a variety of laboratory standards. The field samples were collected primarily from eutrophic waters, although mesotrophic waters were also sampled to create a dynamic range in chlorophyll concentration spanning approximately two orders of magnitude (0.3 25.8 mg m-3). The intercomparisons were used to establish the following: a) the uncertainties in quantitating individual pigments and higher-order variables (sums, ratios, and indices); b) an evaluation of spectrophotometric versus HPLC uncertainties in the determination of total chlorophyll a; and c) the reduction in uncertainties as a result of applying quality assurance (QA) procedures associated with extraction, separation, injection, degradation, detection, calibration, and reporting (particularly limits of detection and quantitation). In addition, the remote sensing requirements for the in situ determination of total chlorophyll a were investigated to determine whether or not the average uncertainty for this measurement is being satisfied. The culmination of the activity was a validation of the round-robin methodology plus the development of the requirements for validating an individual HPLC method. The validation process includes the measurements required to initially demonstrate a pigment is validated, and the measurements that must be made during sample analysis to confirm a method remains validated. The so-called performance-based metrics developed here describe a set of thresholds for a variety of easily-measured parameters with a corresponding set of performance categories. The aggregate set of performance parameters and categories establish a) the overall performance capability of the method, and b) whether or not the capability is consistent with the required accuracy objectives.
