Analytical chemistry is the study of the separation, identification and quantification of the chemical components of natural and artificial materials. Analytical instruments aid in the measurement and testing of these chemical components.
Qualitative analysis gives an indication of the identity of the chemical species in the sample and quantitative analysis determines the amount of one or more of these components.
Providing Necessary Analytical Tools to Achieve Success
Analytical methods can be separated into classical (wet) and instrumental. 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 analytic 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.
