Analytical chemistry is the study of the separation, identification, and quantification of the chemical components of natural and artificial materials. Qualitative analysis gives an indication of the identity of the chemical species in the sample, while quantitative analysis determines the amount of one or more of these components. Analytical methods can be classified as classical and instrumental ones. Classical 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.

Classical Methods

Qualitative analysis determines the presence or absence of a particular compound, but not its mass or concentration.

Chemical test is designed to prove the existence of a chemical compound or chemical group with the aid of a specific reagent.

Flame test is a procedure used in chemistry to detect the presence of certain metal ions, based on each element's characteristic emission spectrum.

Gravimetric analysis involves determining the amount of material present by weighing the sample before and/or after some transformation.

Titration involves the addition of a reactant to a solution being analyzed until some equivalence point is reached.
