Analytical Chemistry:Methods And Applications

by Harold H. Trimm
This collection presents a broad selection of recent research on analytical chemistry, including methods of determination and analysis as applied to plants, pharmaceuticals, foods, proteins, and more. Analytical chemistry is the study of what chemicals are present and in what amount in natural and artificial materials. Because these understandings are fundamental in just about every chemical inquiry, analytical chemistry is used to obtain information, ensure safety, and solve problems in many different chemical areas, and is essential in both theoretical and applied chemistry. Analytical chemistry is driven by new and improved instrumentation.Analytical chemistry is the study of which chemicals are present and in what amount. This often involves trying to determine trace amounts of one chemical in a complicated matrix of other chemicals.Analytical chemistry is driven by new and improved instrumentation. Advances in mass spectrometry, chromatography, electrophoresis, electrochemistry, biosensors, and other instruments are allowing analytical chemists to measure smaller and smaller concentrations of chemicals in complex mixtures. This has direct application to the fields of environmental science, medicine, forensics, food safety, and engineering. The determination of STRs in DNA by capillary electrophoresis, fluorescent dyes, and lasers has led to a revolution in criminal investigation and identification in the field of forensics.Present guidelines for the concentration of chemicals in the air we breathe and water we drink are based on the detection limits that analytical chemists can achieve. Chapters within this book ensure that the analytical chemist can stay current with the latest methods and applications in this important field. |DOWNLOAD||Pages 361||Size 5.55MB|
