Analytical methods can be separated into classical and instrumental
Classical methods or wet chemistry methods : use separations such as precipitation, extraction, and 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.
Analytical chemistry is also focused on improvements in experimental design, chemometrics, and the creation of new measurement tools to provide better chemical information.
Analytical chemistry has applications in forensics, bioanalysis, clinical analysis, environmental analysis, and materials analysis.
