📘 قراءة كتاب Chromatographic Science - Chiral Separations by Liquid Chromatography أونلاين
Biology is a natural science that is concerned with the study of life, its various forms and its function, how these organisms interact with each other and with the surrounding environment. The word biology in Greek is made up of two words: bio (βίος) meaning life. And loggia (-λογία) means science or study. Biology: the similarity of vegetation and animal cover on the edges of the African and American states, and the existence of the same fossil.
Branches of biology
Biology is an ancient science thousands of years old and modern biology began in the nineteenth century. This science has multiple branches. Among them are:
Cytology or cell science
نبذه عن الكتاب:
The development of chiral resolution methods is considered an urgent need in
pharmaceutical, agricultural, and other chemical industries. Perhaps most essential is the development of new chiral drugs, which are necessary because of the
different physiological properties of enantiomers. Various approaches to chiral
resolution have been developed and used, but the direct resolution by liquid
chromatography on chiral stationary phases has proven to be one of the most
effective, practical, and economical. This volume deals with the art of chiral
resolution by liquid chromatography, focusing on high-performance liquid
chromatography (HPLC), sub- and supercritical fluid chromatography (SFC),
capillary electrochromatography (CEC), and thin-layer chromatography (TLC).
These methods are examined as they are used in analysis and development of
drugs, pharmaceuticals, xenobiotics, and other chiral molecules.
The book provides systematic and detailed descriptions of the numerous
approaches to chiral resolution. The first chapter is an introduction to basic
concepts of molecular chirality and liquid chromatography. Chapters 2 through 9
discuss the chiral resolution of various classes of chiral stationary phases. Chapter
10 deals with chiral resolution using chiral mobile phase additives.
