The roots of the periodic table can be traced back to the beginning of the 19th century, when the rapid development of analytical chemistry led to an explosion of new discoveries about elements and compounds.
Analytical chemistry studies and uses instruments and methods used to separate, identify, and quantify matter. In practice separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes. Qualitative analysis identifies analytes, while quantitative analysis determines the numerical amount or concentration.
