Based on the use of high-performance liquid chromatography (HPLC) as a means to assess quantities of separated components in HPLC detectors, this volume is structured for use by analysts who have some experience in chemical analysis or have done HPLC. It keeps theory and instrumentation at a minimum
High performance liquid chromatography is the most powerful of all the chromatographic techniques, often achieving separations and analyses that would be difficult or impossible with other forms of chromatography. This study and training text examines the concepts and techniques used in this field. A selection of literature available from equipment manufacturers is included along with a brief review of some more specialized topics.
High performance liquid chromatography (HPLC) has long been recognized as one of the most useful and versatile analytical techniques. It has now progressed from being a highly expensive method of analysis to a routine technique with wide applications. Consequently there is a requirement in many chemistry and chemistry-related courses for students to acquire a detailed understanding of the principles and practice of HPLC. Written in a manner suitable for undergraduate students studying analytical chemistry and learning about chromatographic analytical techniques applied to pharmaceutical analysis, biochemistry and related disciplines, High-performance Liquid Chromatography: Fundamental Principles and Practice introduces the fundamentals of HPLC. Loosely structured in three parts, the text begins with a thorough introduction of the subject and then progresses through the essential knowledge of the instrumentation needed for HPLC. The final part covers with the applications of HPLC in real-world situations. Developed by a team of international experts from a wide cross-section of disciplines, the text is relevant to a wide range of courses.
High-Performance Liquid Chromatography: Advances and Perspectives, Volume 1 deals with the fundamental aspects of high-performance liquid chromatography, a technique used in chemical analysis. The publication provides accounts, presented by experts in the field, of a variety of topics in high-performance liquid chromatography. Each chapter covers interesting subjects such as the evolution of liquid chromatography; the use of bonded phases in high-performance chromatography; effects of ionization and complex formation on retention and selectivity in reversed-phase chromatography; and gradient elution. Chromatographers, chemists, and researchers in the field of chemical analysis will find this book a valuable reference material.
The book provides an indispensable guide on how to use HPLC in pharmaceutical analysis and drug control. Following a hands-on approach, the authors give practical advices how to prepare stationary and mobile phases, choose a suitable detector and set up an HPLC analysis. The publication gives insight into the key pharmaceutical applications of HPLC and the latest requirements of the major regulatory agencies.
Clinical chemistry is the discipline within laboratory medicine concerned with measuring the concentrations of analytes in blood, body fluids, and tissues. Liquid chromatography is already commonly used in the clinical chemistry laboratory for measuring the concentrations of small molecules, such as drugs and hormones, using a variety of solid phases for separation and numerous detection modalities, most important mass spectrometry. Additional liquid chromatographic methods are now being developed for measuring the concentrations of proteins in blood and tissues, taking advantage of the rapid development of novel mass-spectrometry instruments and methodologies.

In 1906, Michael T. Sweet first developed the chromatographic method by using an adsorbant to separate pigments. Since that time, the technological advances in TLC and HPLC have brought about new definitions of purity in parallel with the advances. Radiopharmaceutical chemistry is especially dependent on the chromat ographic technique because of the relatively small amount of material in most radiopharmaceuticals-often so small that the usual physical methods of analytical chemistry cannot be used. As a result, this collection of papers represents the key to successful radiopharmaceutical development by setting the standard for the pres of radiochemical purity. ent-day definition William C. Eckelman, Ph.D. Diagnostics Associate Director The Squibb Institute for Medical Research New Brunswick, New Jersey Preface The chapters herein are updated and expanded versions of presentations that the authors made at a symposium held on June 4, 1984 in Los Angeles, California under the sponsorship of the Radiopharmaceutical Science Council of the Society of Nuclear Medicine. All manuscripts were refereed. The intent of the symposium organizers was to enlist participants who work on a day-to-day basis with the analytical and chromatographic techniques to be discussed at the symposium. We feel confident that this distillation of hands-on experience will be of value to graduate students as well as experienced researchers in radio pharmaceutical chemistry and related fields which use radiotracer methodology.
Modern liquid column chromatography (LC) has developed rapidly since 1969 to become a standard method of separation. If the statisticians are to be believed, the recent growth of LC has been the most specta cular development in analytical chemistry and has not yet abated be cause its vast potential for application remains to be fully exploit ed. Significant factors contributing to this continued rise are the simplicity and low cost of the required basic equipment and the rela tive ease of acquiring and interpreting the data. Unfortunately, in LC, as so often in the field of analytical chemistry, the available commercial instruments are frequently far more complicated - and consequently far more expensive - than is nec essary for routine application. Therein also lies the risk of propa gating a "black box" philosophy that would be particularly detrimen tal to chromatography. Moreover, it appears to have been forgotten, as was done previously with gas chromatography, that inadequate sep aration by a column can be remedied only with great difficulty, if at all, by electronic means. Also, whether the capillary columns recent ly advocated with great enthusiasm for LC will fulfill the expecta tions of their proponents is highly questionable unless someone comes up with some new and revolutionary ideas.
