Chemical analysis methods

Analytical chemistry consists of classical, wet chemical methods and modern, instrumental methods. Classical qualitative methods use separations such as precipitation, extraction, and distillation. Identification may be based on differences in color, odor, melting point, boiling point, radioactivity or reactivity.
Classical chemical analysis is the basis of Analytical Chemistry. It is of paramount importance that a strong foundation and understanding of principles of chemical analysis is acquired for an understanding and grasp of modern instrumental analytical techniques. The results generated on modern instrumental analysis are as good as your understanding of principles of sampling, matrix isolation ... ----- epa-600/4-79-020 methods for chemical analysis of water and wastes march 1983 second printing june 1982 environmental monitoring and support laboratory office of research and development u s environmental protection agency cincinnati, ohio 45268 printed on recycled paper _

Chemical analyses are used in conjunction with biological and physical parameters to characterize the quality and understand the chemical evolution of fresh water. Standardized analytical methods allow the integration of data collected on disparate waterbodies, regardless of geographic location. Analytical chemistry consists of classical, wet chemical methods and modern, instrumental methods. Classical qualitative methods use separations such as precipitation, extraction, and distillation. Identification may be based on differences in color, odor, melting point, boiling point, radioactivity or reactivity.
Chemical analysis - Chemical analysis - Classical methods: The majority of the classical analytical methods rely on chemical reactions to perform an analysis. In contrast, instrumental methods typically depend on the measurement of a physical property of the analyte. Classical qualitative analysis is performed by adding one or a series of chemical reagents to the analyte. By observing the chemical reactions and their products, one can deduce the identity of the analyte. Physical Methods in Chemical Analysis, Volume III focuses on the application of physical methods in chemical analysis, including chromatography, spectroscopy, nuclear magnetic resonance, and photometry.
