2025年2月21日 · Chemical analysis, chemistry, determination of the physical properties or chemical composition of samples of matter. A large body of systematic procedures intended for these purposes has been continuously evolving in close association with the development of other branches of the physical sciences

Analytical chemistry studies and uses instruments and methods to separate, identify, and quantify matter. [1] In practice, separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes.

Analytical chemistry often is described as the area of chemistry responsible for characterizing the composition of matter, both qualitatively (Is there lead in this paint chip?) and quantitatively (How much lead is in this paint chip?). As we shall see, this description is misleading.
