Separation Techniques

Analytical chemistry is the study of the separation, identification, and quantification of the chemical components of natural and artificial materials. Analytical methods can be separated into classical and instrumental. Classical methods (wet chemistry methods) use  separations such as precipitation, extraction, distillation and qualitative analysis by color, odor, or melting point. Quantitative analysis is achieved by measurement of weight or volume. Instrumental methods use an apparatus to measure physical quantities of the analyte such as light absorption, fluorescence, or conductivity. The separation of materials is accomplished using chromatography or electrophoresis methods
