Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Carbohydrates are ubiquitous. They come as monomers, oligomers and polymers with a startling variety of chemical, physical and material properties. They affect almost every as pect of human live. For example they are an essential part of our nutrition. Cellulose, a car bohydrate polymer, acts as a central material in civilization: as building material for housing and as paper for written communication. Scientifically, the interest in carbohydrates ranges from structural elucidation of simple carbohydrates to fundamental biochemical processes such as photosynthesis and glycolysis. Always, a deeper understanding of a particular aspect of carbohydrate chemistry was accompanied by new methods of measuring and characteri zing this class of molecules. During the last decades a better understanding of the roles of carbohydrates in biochemi cal pathways developed. It turned out, that carbohydrates attached to proteins in glycoprote ins are involved in a number of molecular recognition and targeting processes. This lead to a new research field: Glycobiology. However, unlike for proteins or nucleic acids, there is at this time no consistent theory how chemical composition and structure controls function and inherent information. In order to develop the database, on which new theories and scientific hypothesis are founded, analytical methods to separate compounds with an enormous struc tural diversity and only minor differences in chemical or physical properties has to be deve loped, preferably using only minute quantities.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - During the 1980's the analysis of pharmaceuticals was dominated by the use of High Perfor mance Liquid Chromatography (HPLC). Other separative techniques such as Gas Chromato graphy and Thin Layer Chromatography offered alternatives but their quantitative capabili ties and/or solute range could not approach that of HPLC. The majority of pharmaceuticals are ionic and it would be reasonable to assume that electrophoresis may be useful in the analysis of pharmaceuticals. However, the electrophore tic instruments available in the 1980's were labour intensive and employed post-separation detection procedures. During the late 1980's and early 1990's extensive research was con ducted into the possibilities of conducting electrophoretic separations in capillaries. This approach allowed on-line detection and could be performed on fully automated equipment. This research led to the advent of modern day capillary electrophoresis (CE) instruments which offer similar performance and automation levels to that of HPLC. Research was also focused on developing applications for CE and particular attention was paid to applications within the pharmaceutical analysis area. These applications proved that CE could be applied to a wide range of drug types including water insoluble and neutral compounds. The ability to achieve efficient chiral separations of drugs also increased the popularity of the technique. CE with indirect UV detection has become established as a simple and effective alternative to ion-exchange chromatography for the determination of small inorganic or organic ions.…

Buch. Zustand: Neu. Neuware - This book is intended to be a working guide to the operation of capillary electrophoresis (CE) instrumentation. Since CE is still a rap idly maturing technique, detailed validated protocols are not widely established. Therefore, extensive experimental procedures are not pro vided for individual analyses. The intention is to provide general guide lines on the principles and practice of CE and to give an overview of the specific technologies and important application areas. Part I provides operating instructions for standard commercially available instruments. Guidelines are included for activities such as changing capillaries, method development, quantitative procedures, optimization of precision and sensitivity, and the validation of meth ods, fraction collection, and troubleshooting, as well as a quick guide to running a separation. The application range of CE is possibly the most diverse of all analytical techniques and ranges from large, complex macromolecules, such as proteins and nucleic acids, to small solutes, such as organic drugs and inorganic anions and cations.…
